Teruki Kamon Dark Matter!

Teruki Kamon 2

Quick Quiz: Einstein and Hawking 1) He is the author of a book “A brief history of time”. Who is he? 2) He is famous for this simple equation E = m c2. Who is he?

3) He failed his University Entrance Exam and had to reapply a year later, but received a Nobel prize for photoelectric effect. Who is he?

4) He predicted black-body radiation by black holes. Who is he?

5) On Feb. 11, 2016, scientists announced the detection of gravity waves (GWs) (Sep 14, 2015). GWs are ripples in space-time created by violent collision of two massive black hales in the universe. This was predicted by his theory in 1916. Who is he?

6) He is the first person to point out there is unseen matter (“dark matter”) in the universe. Who is he?

Who Wanted “Dark Matter”?

DM

Darth Vader

“No. I am not your father.”

Fritz Zwicky

(1933) “It’s me.”

Dark Matter in the Universe

Dark Matter and LHC

We relate phenomena at a gigantic scale in the universe to the pp collisions at the Large Hadron Collider (LHC).

Dark Matter in Collisions

1) [E = mc2] Energy in each collision the LHC is transformed to particles just like the first fraction of seconds after the Big Bang.

2) [Particle Telescope] Super-fast detector takes a snapshot of particles in each collision.

3) Study of particles allows us to answer some of big questions. Closer to understanding of the universe.

One of the fastest

racetracks on Earth:

LHC: Proton-Proton Collider

27 km ring

Geneva Airport

CERN

27km-long ultra high vacuum tubes with about one thousand 14.3m-long dipole magnets and 8000 other types of magnets, accelerating protons to 99.999999% of speed of light. You would have to connect 0.6 trillion (600,000,000,000) 12V batteries l

E = mc2 … Mission Possible?

Proton-proton collisions at the LHC can produce the Higgs boson (~130 times heavier than a proton!) along with the electrons and protons, and possibly dark matter particle.

The CMS is one of two super-fast & super-sensitive detectors, consisting of 15 heavy elements, collecting debris from the collision and converting a visual image for us.

We take many pictures of

“debris” of proton-proton

collisions using a super-

fast/super-sensitive detector,

followed by extensive

“detective” analyses to find

evidence of new and rare

phenomena.
