Description
The rare decays Bs->mu+mu- and B0->mu+mu- are highly suppressed in the Standard Model and are thus sensitive probes of contributions due to New Physics particles or interactions. We present the latest results from LHCb in the search for these decays, including in the analysis 1.1/fb of pp collision data accumulated at 8 TeV in 2012.
