[Bfys-physics] LHCb evidence for Bs->mumu
by Marcel Merk 12 Nov '12

12 Nov '12

Dear friends, This morning a preprint was submitted to the arXiv with first (3.5 sigma) evidence of the decay Bs->mumu as well as a first determination of the branching ratio. I am particularly proud of this result since our Nikhef group has made central contributions to: * Theory: together with our Nikhef theory friends we addressed the time integrated vs "t=0" BR. * fs/fd fragmentation: a leading systematic input for the Bs->mumu BR extraction * the selection and background study for Bs->mumu. Congratulations to all people involved! Cheers, - Marcel

Hi all, There's a new paper for us about pp -> pp psi (I'm very glad to see some physics coming out of the very special trigger lines that were added 2 years ago!)
