The Bs  meson is a bound state of a strange quark and a beauty antiquark – as such it possesses both beauty and strangeness! For many years, searches for an extremely rare decay of the Bs meson, to a μ+μ-  pair, remained a holy grail of particle…

The CMS Gas Electron Multiplier (GEM) subsystem will form an extra layer of detectors, along with the Cathode Strip Chambers (CSC) layers, closest to the beam. The GEM's ability to cope with a very high particle rate will greatly improve muon…

New physics may show up at the LHC in the form of yet unobserved particles which travel inside the detector before decaying, far from the point in space where they were produced. If these particles decay to photons, at CMS we can use the short but…

At the EPS-HEP conference this week the CMS collaboration presents new results of a powerful search that is motivated by a variety of new physics models that predict a signature of a bump in the production of the most frequently produced particles…
