Rare particle decay found

After the four years of analysis of LHC data, scientists at CERN have detected a rare decay of a particle known as B0s particle.
Scientist from the CMS and LHCb experiments used the 2011-2012 LHC data to discover the decay of the non-elementary B0s particle into two elementary particles known as muon particles.
“It is testament to the excellent performance of the LHC, and the sensitivity of our experiments, that we have been finally able to observe this extremely rare but important decay”, said LHCb spokesperson Guy Wilkinson.
The theory that describes the world of particles – the Standard Model – predicts that this subatomic process appears about four times out of a billion decays, this However is the first time scientists have recorded the process.
CMS spokesperson Tiziano Camporesi said: “The search for new particles and the study of rare decays are complementary strategies for discovering new physics. The precision with which the experiments can measure these key decay rates will steadily improve, thus limiting the viable extensions to the Standard Model.”
