Add to Calendar 11/2/2018 12:00 pm 11/2/2018 America/Chicago High Energy Phenomenology Seminar: Bs→Kℓν decay from lattice QCD DESCRIPTION:

Semileptonic decays of hadrons can be used to determine elements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The effects of the strong interactions on the decay are encapsulated in form factors. Lattice Quantum Chromodynamics (LQCD) has allowed us to calculate the form factors with increasing precision, making possible stringent tests of the Standard Model and the CKM paradigm. Should two decays that depend on the same CKM matrix element imply different
values for that matrix element, or should there be a violation of unitarity of the CKM matrix, we would have evidence for physics beyond the Standard Model.

In this talk, I will present the most recent results of LQCD calculation of the semileptonic B_s→Klν decay form factors by Fermilab Lattice and MILC Collaborations. I will also present predictions for related phenomenological observables. This decay channel is currently studied by the LHCb experiment and it is also expected to be studied by the Belle II experiment.
