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...

Not many people know that there is a boson-boson collider hiding in the proton-proton collisions of the Large Hadron Collider. The idea is that during rare occasions other particles such as the photon and gauge bosons W and Z are created by the...

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...
