Title: Semileptonic decays of B mesons from lattice QCD

Speaker: Dr. Chris Monahan (Institute of Nuclear Theory, Washington)

Abstract: Where is all the new physics hiding? In spite of enormous successes, such as the discovery of the Higgs boson, and a mountain of data, direct searches at the LHC--the energy frontier--have so far failed to turn up new fundamental particles. An alternative approach is to hunt for answers at the intensity frontier: the possibility of new physics lurks in tantalising discrepancies between theoretical predictions and experimental observations in the flavour physics sector. The Cabibbo-Kobayashi-Maskawa (CKM) matrix, which describes the mixing of quark mass eigenstates under the weak force, is unitary in the Standard Model. By constraining CKM matrix parameters through measurements of multiple different processes, any observations of deviations from unitarity may hint at new physics effects. Key to this program are precise theoretical predictions, which require lattice QCD calculations of hadronic contributions to Standard Model processes. I review the latest lattice calculations of B meson decays from the HPQCD collaboration and highlight the role of results from LHCb, which are expected in the near future.
