Physicists continue to question if the particles we know of are the most fundamental. A new result by the CMS collaboration examines the data collected between 2016 and 2018 for evidence that quarks are composite particles and not elementary.  Since…

Studying the production of two Higgs bosons is the most obvious way to understand the field responsible for the Higgs boson. A new result by the CMS collaboration gets closer than ever to measuring this field and its physics prediction. The Higgs…

What if new particles modify the behaviour of existing particles, but by only a little bit? In a new result, CMS physicists search for new physics using a technique called Effective Field Theory to study the top quark in a "toy universe". We have…

CMS has just finished wrapping the barrel with a new layer which is not a new detector but a brand new protection system aimed to keep the outer barrel muon chambers shielded from background radiation present in the experimental cavern during…
