Abstract:

Understanding the matter-antimatter asymmetry of the Universe is a primary goal of the LHCb experiment, through precision measurements of CP violation in b decays.
After a brief introduction to the LHCb detector, I will show some recent results on CP violation measurements with a special focus on the weak phase gamma and on three-body charmless B decays. The state-of-the-art global fit results of the CKM matrix from the CKMfitter group will also be presented. In the end, I will introduce an amplitude analysis tool that we have developed to understand the nature of CP violation in multi-body decays.

 

Biography:

Wenbin Qian is currently an associated professor with tenure at University of Chinese Academy of Sciences. He obtained his Ph. D degree in the field of experimental particle physics from Tsinghua University and University of Paris-Saclay. He was a post-doc in Syracuse University, LAPP CNRS and University of Oxford and a Marie-curie individual fellow in University of Warwick. His main physics interest lies in searching for new sources of CP violation through precision measurements in B decays.
