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...

A new result released by the CMS Collaboration presents the first evidence of the Higgs boson interacting with the muon. The standard model of particle physics describes all the known fundamental particles in the Universe. A mystery of the standard...

In 2012 the ATLAS and CMS collaborations discovered a boson with a mass of 125 GeV, i.e. approximately 125 times the mass of the proton, in proton-proton collisions at the CERN LHC. This has marked a milestone in high energy physics, as this...

Measuring the interaction between the Higgs boson and other particles is essential to understand if the particle behaves consistently with predictions. For the International Conference of High Energy Physics 2020, the CMS experiment has released new...

A question researchers at the LHC are trying to answer is whether the properties of the Higgs boson are as predicted by the standard model. One way to do this is to look for extremely rare decays of the Higgs boson, as physicists in the CMS...

Eight years ago, at the largest International Conference on High Energy Physics (ICHEP), the discovery of a new particle carefully coined as Higgs boson-like was announced by the ATLAS and CMS Collaborations. They had seen an excess in data over...

The Higgs boson is an extremely rare particle. At the Large Hadron Collider (LHC), where bunches of protons collide at more than 99.9999% of the speed of light up to forty million times per second, a Higgs is produced around once per second. The...

In 2012 the CMS and ATLAS Collaborations announced the discovery of a new particle, that seems mostly consistent with the Higgs boson as predicted by the Standard Model. To understand if that is actually the case, physicists in the CMS collaboration...

The CMS collaboration has released the first observation of the simultaneous production of three W or Z bosons in proton-proton collisions at the Large Hadron Collider (LHC). The result is based on the data collected by CMS during 2016–2018 at a...

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...
