High Energy Seminar
Fully Leptonic Charged B Decays at Babar.
- Time: 4:00 pm
- Place: 4274 Chamberlin
- Speaker: Dr. Luke Corwin, Indiana University
- Abstract: The Babar detector was a multi-purpose particle physics detector
at the PEP-II accelerator in SLAC National Laboratory. It is named after
its primary objects of study, the B mesons, and a cartoon elephant. The
accelerator was tuned to produce the Upsilon(4S) resonance, which almost
always decays into a pair of B mesons. In this talk, I will describe the
challenges and methods of searching for events in which a charged B decays
into a charged lepton and a neutrino. The primary focus will be the search
for charged B mesons decaying into a tau lepton and a neutrino in the recoil
of a semi-leptonically decaying B. I will review complementary searches at
Babar and the Belle experiment in Japan, and I will present the implications
of these results for physics beyond the Standard Model.
