First evidence for Bs->mumu: theoretical overview and experimental result

by Gino Isidori (INFN Frascati), Xabier Cid Vidal (Universidade de Santiago de Compostela (ES))

Thursday, 7 February 2013 from to (Europe/Zurich)
at CERN ( 4-2-011 - TH common room )
In the first part, Gino Isidori will review the theoretical interest of Bs -> mu mu, both within and beyond the SM, discussing in particular the uncertainties affecting the SM prediction. Then Xabier Cid Vidal will explain the search for Bs -> mu mu using 2.1 fb^-1 of LHCb data, leading to a 3.5sigma evidence. He will describe the experimental challenges of this channel and summarize the techniques employed.
