Could you imagine what the dark part of the universe is like?  The Standard Model of Particle Physics explains matter at the subatomic level and the related phenomena such as interactions and forces between the subatomic particles. Still, we already…

  For the first time, CMS physicists extract the fundamental parameters of QCD together with constraints on the New Physics.  Any tiny failure of the Standard Model to explain data behaviour is a possible window for the New Physics. An example is…
