Abstract :

SuperKEKB is an intensity-frontier particle accelerator that is designed to reach an instantaneous luminosity of 6 x 10^35 cm^-2s^-1. Operating at a centre-of-mass energy corresponding to the peak of the Upsilon(4S) resonance, the goal is accumulating a data sample corresponding to an integrated luminosity of 50 ab^-1. The sample will contain billions of B mesons, charm hadrons and tau leptons that the Belle II experiment will use to search for rare decays and perform precision measurements of flavour observables. These searches and measurements allow indirect probes of physics beyond the standard model. This talk will motivate the Belle II physics programme, before briefly describing SuperKEKB and the Belle II experiment. Some recent results related to charm decays, measurements of the Unitarity Triangle and the so-called B anomalies will be presented.

ABOUT THE SPEAKER:

Jim Libby is an experimental particle physicist. He received his Ph.D. from the University of Oxford for studies of electroweak physics with the DELPHI experiment at CERN. Since then he has worked primarily on flavour physics focusing on measurements of matter-antimatter asymmetry in decays of the beauty and charm hadrons, as well as rare decays and instrumentation. He has held research positions at Stanford, CERN and the University of Oxford, while working on LHCb, BaBar and CLEO-c experiments. He has been a member of the IITM faculty since 2009 working primarily on Belle and Belle II.
