Public Lecture | Starting From the Bottom: The Hunt for New Physics at the LHC

The Large Hadron Collider (LHC), the giant particle accelerator at the CERN laboratory in Geneva, Switzerland, will restart operations in 2015, at higher energies and intensities than ever before. In its first run, the LHC experiments ATLAS and CMS discovered the long-sought Higgs boson. Now, researchers are gearing up to search for new and even more exotic phenomena. Many of the possibilities involve particles that decay to the bottom quark, a rare and unusual species of quark with a distinctive appearance in particle detectors. Identifying and measuring bottom quarks in LHC collisions requires extremely high-speed silicon pixel detectors. In this lecture, SLAC's Michael Kagan describes the cutting-edge technology used to image bottom quarks and its use in the search for new types of elementary particles that might appear at very high energies.
About the Speaker:
Michael Kagan studied physics and mathematics at the University of Michigan, graduating in 2006. He obtained his PhD from Harvard University in 2012 for his work on measurements of the W and Z bosons with the ATLAS experiment at the LHC. He joined SLAC in 2012 as a research associate. In this role, he has spent a large portion of his time at CERN helping to build a new layer of high-speed silicon pixel detectors for the ATLAS experiment. He also works on improving pattern recognition algorithms for finding b quarks in ATLAS data and using these b quarks to study Higgs bosons and search for exotic signatures of new physics.

Dear SLAC National Accelerator Laboratory =),
I would like to say, thank you, for taking the time and effort to both upload and share this video with the youtube family =).
I hope you have a nice day!
Kind Regards
Raymond Lai (Member of the Physics Family)

Jesus Christ, this was the information I was looking for as to how particle detectors work, but i needed to watch this 3 times as a laymen. And I read "The Particle at the End of the Universe"
Still, I'm lovin' it.

[@afederdk]

Very informative, thank you. It finally makes sense how it is even remotely possible to measure anything on those scales.

Fantastic presentation!

Amazing ;)

I have a theory: dark energy condenses into dark matter, which in turn condenses into visible, ordinary matter :- hydrogen. Apart from frequencies and wavelengths, there is no difference between ordinary matter, dark matter and dark energy. My theory is supported by the discovery, by astronomers, of a "bridge" pf hydrogen connecting Andromeda and Triangulum, and also of a "wall" of hydrogen surrounding the outskirt of the solar system. My theory also explains why hydrogen is the most abundant element in the universe. No wonder, because 75% of the mass of the universe are waiting for their turns to condense into hydrogen.

Hmmm... Where's all of the doomsday woo? It was pretty thick on the way here.

I have a few of those trillion electron volt mosquitoes around here.

*BLASPHEMY!!!! I just checked my bible and there is no mention of the god particle.*
