High Energy Physics Seminar: Beauty Quarks behaving awkwardly, or is New Physics hiding in flavor?

The Department of Physics welcomes Dr.  Rafael Silva Coutinho, who will be presenting a seminar. Dr. Coutinho is currently a postdoctoral researcher at the University of Zurich, mainly involved in searches for lepton flavor universality breaking in rare decays of B mesons. He obtained his Ph.D. from the University of Warwick, where his work focused on the searches for asymmetries in the decays of neutral B mesons and beauty baryons to final states containing long-lived particles.


While the Standard Model of particle physics successfully describes all known particles and their interactions, it is broadly accepted that it is an incomplete description of Nature. It predicts that particles known as beauty quarks should decay into final states involving either muons or electrons at equal rates. However, recent data from CERN’s LHCb experiment suggests that this is not the case. Could this be evidence for the long-awaited “New Physics”? Or are the measurements or the Standard Model predictions not all they seem? In this seminar, an overview of the latest results in this sector and possible interpretations are discussed.
