This week, the seminar speaker is our very own Chris Bouchard, who recently joined us as a postdoc. I encourage you to come and welcome him to the department.


The CKM matrix element Vub plays an important role in the search for cracks in the standard model accommodation of flavor changing interactions. Processes currently used to determine Vub (exclusive B ? ? l ?, inclusive B ? Xu l ?, and B ? ? ?) produce an inconsistent picture, with a ~3 sigma tension between the two, more precise, semileptonic decays. Alternative decays, including Bs ? K l ?, may help clarify the situation. I will present the first lattice QCD results for the form factors for this decay and discuss their phenomenological implications.
