For the first time, CMS physicists have investigated an effect called the “running” of the top quark mass, a fundamental quantum effect predicted by the Standard Model. Mass is one of the most complex concepts in fundamental physics, which went...

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...
