Newswire: 19 July 2013 - CERN - CERN experiments put Standard Model to stringent test

Geneva, 19 July 2013. New results to be presented at the EPS-HEP conference in Stockholm, Sweden, this afternoon have put the Standard Model of particle physics to one of its most stringent tests to date. The CMS and LHCb experiments at CERN's[1] Large Hadron Collider will present measurements of one of the rarest measureable processes in physics: the decay of a Bs (pronounced B-sub-s) particle into two muons.
