To investigate when the Standard Model will start breaking down, the CMS Experiment looks at extremely rare collisions where the Large Hadron Collider is working as a boson-boson collider. This can teach us more about the nature of the Higgs boson...

New, undiscovered charged particles could be produced by the LHC, leaving tracks in CMS that look similar to tracks from Standard Model particles. If the new particle decays to other, unseen new particles inside the CMS tracker, a very striking...

At the LHC, protons do not collide one at a time. Instead, the protons are combined into bunches, packages of more than 100,000 million (1011) protons. These bunches are then pointed at each other at the four collision points of the LHC. Even when...

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...
