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?, B0s ? µ+µ-, B0 ? K*+-, and CP violation in the B0 and B0s systems. Hints of deviations from Standard Model predictions from other decays including B- ? t-?, and B ? D(*)t-? are investigated. Finally, searches for dark matter and Majorana neutrinos are reviewed.
