CPT Student Seminar: Charming new physics in b(eautiful) processes?

Presented by Matthew Kirk, University of Durham

13 March 2017 17:00 in OC218

There are a number of intriguing anomalies in rare B meson decays, which could indicate the presence of beyond the Standard Model physics. I will give some background on these anomalies, and then describe some recent work where we attempted to explain one of the anomalies using a model-independent approach.
I will show how by looking at 4-quark operators of the form (bs)(cc), we can explain one of the anomalies while still agreeing with very strong constraints from other rare B decays, due to large renormalisation group effects.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
