This is not a Summary-- I was not asked to give one --

These are not `the’ Conclusions

-- the `Boss’ M. Calvetti has still to speak

(a US Supreme Court Justice once said:”We are not theSupreme Court because we are infallible; we are infallible,

because we are the Supreme, i.e. final court.) --

these are merely my personal reflections.

“What do we need to know to understandmore?”

A short look back:

Exhibit A

✒The weak bosons were first found at the CERN SPS -- ahadronic collider;

✒ it was LEP I & II -- an e+e- machine -- that establishedthe gauge structure of the SM with a quantitative accuracywell beyond original expectations

3

Exhibit B

✒ Indirect and direct CP were first found at BNL and at the CERN SPS & FNAL -- hadronic machines;

✒ the B factories at KEK & Stanford -- e+e- machines -- established Yukawa sector: CKM dynamics able to describe (at least almost all) CP observed in particle transitions to a quantitative accuracy well beyond original expectations

All New Physics at that time

-- yet now pillars of the SM!

Past indirect searches for New Physics -- memento D S ≠ 0 dynamics:

5

None of the successes of the SM invalidate the argumentsfor it being incomplete:

New Physics has to exist --

a virtual consensus in the community.

Clear majority opinion:

Need more answers/hints from nature to

❏ figure out variant of New Physics realized in nature

❏ confirm we are on `right track’:

“Experiment is the Supreme Court of Physics”

6

Given the past history of searches for Physics beyond

the SM, you might think of …

7

S. Beckett:”Ever tried? Ever failed?

No matter.Try again. Fail again. Fail better.

8

Cheer up --

we know there is New Physics:

❏ baryogenesis➥ the new CP Paradigm!

❏ neutrino oscillations❏ dark matter❏ dark energy❏ explanatory deficits

-- we will not fail forever!

9

Yet history never repeats itself in an identical way!

☞ We cannot count on numerically massive impacts ofthe conjectured New Physics

Nature apparently has read the SM’s book on FlChNC --

at least for down-type quarks

10

A. Masiero: ”You have to be lucky to find New Physics.”

Napoleon:”Being lucky is part of the job description for my generals!”

Accuracy in acquiring & interpreting data will do wonders for our `luck’

☞ heavy flavour studies❏ are of fundamental importance; ❏ its lessons cannot be obtained any other way; ❏ cannot become obsolete. i.e., no matter what studies of high pt physics at FNAL & LHC will or will not show -- comprehensive & detailed studies of flavour dynamics will remain crucial in our efforts to reveal Nature’s Grand Design

11

3 scenarios for the next 5 - 8 years outA -- the optimal one:

new physics observed at high pt (FNAL/LHC)➥ must study their impact on flavour dynamics

some features -- mass scale etc. known !

B -- the intriguing onedeviations from SM established in heavy flavour decays

C -- the frustrating oneno deviation from SM prediction identified

✒ none of these scenarios weakens the role of flavourstudies being essential for coming to grips withnature’s `Grand Design’

12

The generalized `Nakada Concern’:

While we have more promising avenues for exploringfundamental physics than ever,

While we have more technical abilities & tools than ever,

We live in a world with immense political, social, environmental … problems and

have to deal with governments with less interest in basicresearch to a degree that goes well beyond a justified pre-occupation with these problems --

How do we choose our priorities?

13

Be comprehensive:

A Super-B factory is also a 3rd family down-type quark

✒ Super-Tau as well as 3rd family down-type lepton

✒ Super-Charm factory 2nd family up-type quark

of truly unique capabilities

NB:

Studies of CP, oscillations & rare decays instrumentalized toprobe & analyze TeV scale New Physics

… and

❏ Is Solution 2 (see Biagini’s talk) portable to -- KEK?

To me it is mandatory to study the idea of such a novel`ILC inspired’ Super-B factory with the utmost

dedication

Is it a setting or is it a rising sun?
