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

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.
