Title

Disintegration of beauty: a precision study

Speaker

Dr. Hiroyuki Umeeda (Institute of Physics, Academia Sinica)

Abstract

The lifetime of B meson is one of the primary observables for testing weak and strong interactions in the standard model. The theoretical analysis for this quantity is performed on the basis of the heavy quark expansion, where an inverse of bottom quark mass is treated as an expansion parameter. I will talk about [2208.02643], where the analysis is updated in such a way that the power correction terms are made more precise.
