| Abstract: | From the hierarchy problem to gauge unification to dark matter, supersymmetry provides elegant solutions to many of today's pressing theoretical problems. A natural supersymmetric solution to the hierarchy problem strongly implies light third-generation scalar quarks, which makes analyses targeting such final states among the most well-motivated of new physics searches. This seminar will focus on the most recent ATLAS searches for scalar bottom production and gluino-mediated scalar top and bottom production in hadronic final states with b-tagged jets and missing transverse momentum. The advantages of the "simplified models" approach to designing broadly sensitive searches will also be discussed. |
| Speaker: | Bart Butler - SLAC
 Mr. Butler received his undergraduate degree from Dartmouth College in Physics and Chemistry in June, 2006, and began work on BaBar data analysis in David MacFarlane's group at SLAC a month later. He then joined the SLAC ATLAS group in January, 2007, and since then has spent 3 years in residence at CERN, working on the ATLAS pixel detector, track jets and calorimeter jets, supersymmetry searches, and software development. He hopes to graduate soon.
