Context

• People with opinions just go around bothering one another.– Buddha

• Science is a wonderful thing if one doesn’t have to earn one’s living at it.– Einstein

• Physics is not religion. If it were, we’d have a much easier time raising money.– Leon Lederman

What is Science?

• What is science…– … as a way of thinking?– … as a way of communicating?– … as a way of experiencing the world?– ... as a way of learning about the world?

• British Science Council said:– “Science is the pursuit and application of knowledge and

understanding of the natural and social world following a systematic methodology based on evidence.”

• Homework: What is research? What is development?

20 Aug 2014

5

Why?

• Many of us agree that science is valuable…but why?

• Why is science important to our society?• Why is it publicly funded (at all)?

• If science is an intellectual/cultural pursuit that “enriches us,”– Why does the U.S. spend more public funds on science &

technology than the performing & visual arts?

20 Aug 2014

6

Assertions (i.e., never fully proven)

• Science drives benefits in multiple sectors & at multiple scales– These benefits are of broad and

shared value– These benefits take “unusual” time &

effort to develop or accrue

• Generally agreed that these benefits fall in three categories– Satisfy / fulfill human curiosity– Inspire / train the next generation– Create jobs / stimulate economic

activity in medium and long-term

Ergo…

• Conclusion– It is good public policy to support science with taxpayer funds so that

the benefits & impacts are optimally generated---and captured---for society

• This line of reasoning can create a sense of obligation or civic duty about sharing the benefits, progress, and story of science with the public

20 Aug 2014

What distinguishes particle physics?

• Its area of interest– Building blocks, interactions, space/matter,

energy/time, …

• Its techniques and approaches: ways of analysis– Statistics & data mining, theoretical models &

experiment, large instruments & teams, …

• Its value & contribution– Stretches technology in unusual fashion

• And today’s thesis: its promotion of world peace

Tradition of international partnerships in particle physics

• Founding of CERN in 1950s• Canada joins HERA at DESY…• …CDF/D0, ATLAS/CMS, and so on

– Thousands of scientists and students from around the world pool talent & resources to attack compelling questions

• Today’s recipe– Effective international collaboration

means participation in the accelerator, the detector, and the computing – to share in the physics

• Particle physics has enjoyed its reputation as one of the founding disciplines for “science diplomacy”

20 Aug 2014

Science diplomacy

• “Science diplomacy is the use of scientific collaborations among nations to address common problems and to build constructive international partnerships. Many experts and groups use a variety of definitions for science diplomacy. However, science diplomacy has become an umbrella term to describe a number of formal or informal technical, research-based, academic or engineering exchanges.”– Wikipedia

• U.S. president John F. Kennedy established formal S&T cooperation agreement with Japan in 1961 following appeals to repair the “broken dialogue” between the two countries

– That agreement helped grow the tenuous relationship beyond just security concerns.

• In the 1970s, Henry Kissinger took science initiatives to his meetings with China – In 1979, when official diplomatic ties were established between China and the U.S.,

science played a big role in the shaping of renewed efforts.

• SESAME – particle physics & “light-source” science creating a platform for peaceful cooperation in the Middle East

20 Aug 2014

11

But…is this model still working?

• The driver for international partnerships has been two-fold– Using common language of science, share the physics and build

relationships among countries & cultures– Affordability: need to pool resources & talents -- not everyone can

build a particle-physics experiment on their own

• But the WAY in which we think “international” is evolving under strain– SSC, KAON, ITER?– Global Design Effort for ILC (now LC, but used to be NLC, JLC)

• Increased pressure for coordinated planning…and investment– The world can have only “one” of each multi-billion-dollar project– Which ones? Where? In what order?

20 Aug 2014

12

A lot of thinking has been going on about this…

• U.S. National Academies decadal plan for particle physics (2006)– (I acknowledge this as an immodest self-reference)

– “‘Science is a global enterprise in which the United States must participate, for its own benefit and for that of the world.’ … That is, to remain competitive, the United States must seek collaborations that confer mutual advantage.”

– “The [U.S.] nation can benefit by developing ‘mutual gain’ policies. Doing so requires a fundamental change in global strategy. The United States should move away from an almost certainly futile attempt to maintain dominance and toward an approach in which leadership comes from developing and brokering mutual gains among equal partners….It comes not from self-sufficiency or maintaining a monopoly but from being a valued collaborator at various levels in the international system.”

“Dinner party” models for international partnership

• Buffet– We prepare and serve; you come and eat

• Set menu– We’re cooking this; what part can you bring?

• Potluck– Let’s have dinner; I’ll bring this, you bring something that

goes with it

• Dinner time– Are you hungry? Want to have dinner together?– What should we have & who else can we invite?

(2013 Update of the) European Strategy for Particle Physics

• Of the first six recommendations, four take an explicit position on how to think & plan globally

– “[The] scale of the facilities required by particle physics is resulting in the globalisation of the field. The European Strategy takes into account the worldwide particle physics landscape…”

– “CERN should undertake design studies for accelerator projects in a global context, with emphasis on proton-proton and electron-positron high-energy frontier machines.”

– “[The] initiative from the Japanese particle physics community to host the ILC in Japan is most welcome, and European groups are eager to participate. Europe looks forward to a proposal from Japan to discuss a possible participation.”

– “CERN should develop a neutrino programme to pave the way for a substantial European role in future long-baseline experiments. Europe should explore the possibility of major participation in leading long-baseline neutrino projects in the US and Japan.”

Rewind/Zoom Out: Broader Context

• U.S. particle physics (still) at a crossroads– ~Half the community works on LHC at CERN– Tevatron at Fermilab has ceased operations– Higgs has been found; what’s next?– Faltering enthusiasm for decisive participation in “an” ILC– Public funds for research are squeezed more than ever

• In 2013, U.S. Particle Physics Project Prioritization Panel (P5) was charged with synthesizing community expressions of scientific opportunity (from Snowmass process) into a strategic plan that could be executed over a decade under several different budget scenarios

• As nation’s primary lab for particle physics, Fermilab keen on P5 report

Fermilab by the Numbers

• Fermilab has 1,700 employees on a 6,800 acre site with an annual operating budget of $350M-$400M

• Making the lab open and available to scientists, students, and citizens across the country and around the world is a priority– 2,100 scientists visit from around the world– 40,000 K-12 students participate in activities at Fermilab or are visited in

classrooms by Fermilab staff– 8,000 visitors took tours or visited Lederman Science Center– 1,000 college & university students involved in on-site programs or internships

• Basic research advances the economy. In FY 2010:– Fermilab created 4,529 jobs in Illinois.– Fermilab generated $643 million of regional economic activity

Fermilab’s role in exposing the “quantum universe”

20 Aug 201420

Neutrinos are abundant in our world

20 Aug 201421

22

Neutrinos are different

• Neutrinos are difficult to study because they interact with ordinary matter only through the weak interactions– Easily travel through a light-year of lead – They have their own mixing, which may or may not have the

same origins as quark mixing– Neutrinos oscillate a billion times slower than neutral mesons

oscillate

• 100 billion/sec pass through your thumbnail w/o a trace

• Neutrinos created about 1 second after the Big Bang remain all around us today : 150 per cubic centimeter

• More than any other matter particle in the universe

20 Aug 2014

23

Neutrinos…curiouser and curiouser

• The wide range of quark masses is puzzling– The top quark discovery was an exclamation mark on that

• The ultra-tiny neutrino mass doesn’t fit the standard model– In fact we do not understand neutrinos mass, other than it has mass

• The Higgs discovery has brought flavor and mass issues to the forefront

• One future lies in better understanding neutrinos – Their mass ordering– The origin of their masses and why they are so small– Their interactions (CP Violation)– Their relationship to matter-antimatter asymmetry in universe

(leptogenesis) and structure of the universe

U.S. P5 report on long-baseline neutrinos

• “To address even the minimum requirements…the expertise and resources of the international neutrino community are needed. A change in approach is therefore required. The activity should be reformulated under the auspices of a new international collaboration, as an internationally coordinated and internationally funded program, with Fermilab as host. There should be international participation in defining the program’s scope and capabilities. The experiment should be designed, constructed, and operated by the international collaboration. The goal should be to achieve, and even exceed if physics eventually demands, the target requirements through the broadest possible international participation.”

20 Aug 2014

33

P5 on neutrinos: “Reformulate under the auspices…”

• This recommendation is perhaps the boldest and the most strategic element of the P5 vision– The U.S. can demonstrate leadership by convening international

conversation to develop a mutually agreeable/shared program– The U.S. should consider itself as “host” to an internationally relevant

“facility” (not just a collaborative experiment)– The global value of the facility should be based on aggressive and

competitive neutrino-beam power at Fermilab– The program should coherently pursue the physics through both

“short-baseline” and “long-baseline” approaches

• The world community is taking its homework seriously

20 Aug 2014

Long-Baseline Program Process (1)

• June 16: CERN Science Policy Committee (SPC) presentation…US situation and plans post-P5– Chairs of CERN Council & Finance Committee present

• CERN Medium-Term Plan (MTP) approved…5 year plan with next year’s budget defined…$60M for neutrinos– Aimed at neutrino platform to assist with program in US– Investment in infrastructure outside CERN allowed– No funds for a CERN neutrino beam for at least 5 years

• June 21-22: APPEC Paris meeting…European neutrino physicists & agencies met to discuss future post-MTP– World program represented– Strong support for accelerator-based neutrinos in US & Japan– Next meeting at Fermilab in spring

34 20 Aug 2014

Long-Baseline Program Process (2)

• July 14: U.S. DOE hosted a meeting at Fermilab of funding agencies….UK, Italy, CERN, India, Brazil, Japan– Governance discussion started– Project management (embed international components in

Lehman-like process)– Launch steering committee to develop international PMP

• July 21-22: “Neutrino Summit” hosted at Fermilab– Ken Long & Rob Roser, Co-Chairs– Confirm global interest and identify areas of agreement and

areas for decision-making– Commit to formation of interim international Executive Board

steering group along with framework for technical working groups

35 20 Aug 2014

36

Long-Baseline Program Process (3)

• July 23-25: Fermilab Physics Advisory Committee discussions of SBN + LBN programs; support iiEB approach and systematic inclusion of international partners

• Sep 2014: expect first meeting of iiEB as well as informal draft of International Project Management Plan

• Goals:– Form SBN collaboration to develop community, technology, and

research as platform for LBN– Letter of intent for “competitive, long-baseline neutrino experiment

using beams from Fermilab” submitted to PAC by early 2015– List of authors/collaborators will form basis of new collaboration that

joins together all willing partners

20 Aug 2014

37

The Broader Future of Fermilab

• Particle physics– “Explore the unknown” with muon physics– Platform for U.S. participation in LHC– Highest-power beams for world’s highest-priority accelerator-

based neutrino experiments– Dark matter & dark energy

• Accelerators– SC magnets & SRF cavities/cryomodules– Platform for U.S. developing role in ILC– Pioneer industrial engagement & tech. commercialization

20 Aug 2014

Outlook (1)

• Fermilab is committed to hosting the most competitive accelerator-based neutrino program for the world– “We propose to have an open discussion that entertains all

views as to how best to design an international facility so that we optimize the physics outcome within agreed-upon constraints...”

• We cannot begin the whole planning process over, and in fact, that would be foolish – don’t want to throw away hard work. – But for a new level of engagement & participation from other

countries, substantive discussions have to place and we have to be willing to change our minds

38 20 Aug 2014

39

Outlook (2)

• Particle physics has the opportunity (again) to set the trend for international scientific partnership & participation– LBN provide an obvious opportunity b/c even without a formal,

top-down global strategy, three regions of the world have identified it as a high priority effort

• This will be a test case!– If we succeed, world peace is one step closer
