New physics from flavour

Abstract

I report on investigations of physics beyond the Standard Model using experiments designed to investigate $b$ quark and $c$ quark interactions. Generalized searches involving loop diagrams using heavy meson mixing and CP violation experiments imply limits on New Physics (NP) at large scales from 100-100,000 TeV. There are ways of avoiding these limits, but satisfying their requirements puts severe restrictions on NP properties. Specific constraints on NP models are discussed from individual measurements including b-> s gamma, Bs->mu+ mu-, B0 -> K* l+ l-, and CP violation in the B0 and Bs systems. Hints of deviations from Standard Model predictions from other decays including B- -> tau- nu, and B->D(*)tau- nu$\ are investigated. Finally, searches for dark matter and Majorana neutrinos are reviewed.
