It is the dream of all particle physicists to find a new particle or to reveal a new fundamental force. In 2012 this dream came true when the big CERN experiments ATLAS and CMS discovered the Higgs particle, predicted by theorists decades ago. Other...

Have you ever pondered what happened to our Universe after the Big Bang? When the Universe was created, each particle was produced together with its antiparticle. For example, for each electron we see now, there was a positron created. But, some 13...

Identification of muons is essential for the physics done at the LHC. CMS has recently published a paper with new techniques to identify muons with high momentum. What is so special about muons with high momentum that they deserve a dedicated paper...

The CMS collaboration has achieved the first observation of a ttH process in a single Higgs boson decay channel. The Higgs boson is examined in its decay to two photons when produced alongside a top quark and antiquark. This enables the measurement...
