Description | HE Seminar Speaker: Wells Wulsin, Stanford University Title:Charmless semileptonic B decays and |Vub| at BaBar Host: Robin Erbacher Room: 416 The magnitude of Vub can be used to test for physics beyond the Standard Model by placing a redundant constraint on the unitarity of the CKM matrix. I will present the results of two exclusive measurements of |Vub|, using B-->(pi/rho) l nu and B-->omega l nu decays. The combined study of B-->pi l nu and B-->rho l nu has made one of the most precise single determinations of |Vub|. The B-->omega l nu analysis uses data from the omega mass sidebands to describe the dominant background, and has made the first measurement of the B-->omega l nu q2 spectrum. |
