[email protected] Your Your life life with with CLEO CLEO++ BTEV BTEV GSAC: Mats Selen, February 24, 2001 The bottom line: We are a small, friendly, well supported group of particle physicists. We work on a variety of interesting physics topics. We contribute significantly
to the design & construction of detectors and electronics. I am looking for (~2) enthusiastic students that like to roll up their sleeves & dive into some fascinating work.

D* q2max Last CLEO result: PRD 51, 1014 (1995) This is where the money is (q2max) ! [email protected][email protected] BTeV BTeV B meson decays can tell us a lot about the Standard Model (and beyond), but we need more data. For the next 5 years, B physics will be dominated by BaBar (SLAC), Belle (KEK) and CDF/D0 (FNAL). BTEV is a new experiment (ready in 5 years) that will dominate B physics in the LHC era.
BTEV will collect more useable B data in a few days than the e+e- B Factories do in a year. Motivation: Vud V V CKM cd V td Vus Vub Vcs Vcb Vts Vtb [email protected] BTeV BTeV
