Nuclear and Particle Physics Colloquium 24

Speaker: Dr. Jorge Martin Gamalich, the University of Mainz, Germany

Abstract:

Anomalies in (semi)leptonic B-meson decays present interesting patterns that might be revealing the shape of the new physics to come. I will review the decays and observables where these appear, discussing the extent up to which the respective SM predictions are understood. In this sense, the most interesting anomaly is the violation of lepton universality suggested by a recent measurement of a deficit of B+？K+μμ over B+？K+ee decays. This raises very interesting questions concerning the lepton-flavor structure of the presumed new interactions, some of which I will address in the context of effective operators and a particular class of models of new physics. Finally, I will discuss new possible experiments that could unambiguously confirm and characterize the putative new-physics effect.

About the speaker: Dr Jorge Martin Camalich obtained his Ph.D. degree under the supervision of Prof Manolo J. Vicente Vacas in 2010, from the University of Valencia. His thesis, "Properties of baryons in chiral perturbation theory" received the 1st extraordinary award from the University of Valencia and the European Physical Society award for the best thesis in Nuclear theory for the period 2009-2011. After his thesis Dr Martin Camalich spent 3 years in the University of Sussex where he started working on the search for new-physics in rare B-decays. In 2013 he obtained a prestigious Marie-Curie grant and moved to the University of California, San Diego, where he worked on the analysis and interpretation of different B-physics anomalies in collaboration with Prof Ben Grinstein. In 2015 he moved to the University of Mainz. He has published 25 articles in journals of high impact, including 5 papers in Physics Review Letters and accumulates ~1000 citations in inSPIRES with a h-factor of 19.
