Since the LHC first began colliding protons over ten years ago, CMS physicists have hoped to find evidence for one of the most popular and expansive theories of New Physics -- Supersymmetry.   The key idea of Supersymmetry (or “SUSY”) is to add a…

The term 'flavor' was introduced by Murray Gell-Mann and his student Harald Fritzsch to describe the different types of quarks known at the time – up, down, and strange – the list of quark flavors grew to six. The term is adapted for the lepton…

  Are there more fundamental particles than the ones we currently know? Do we live in a Universe with additional spatial dimensions? These hypotheses are among the many ideas that have been suggested to explain how to unify the electroweak and…

The CMS Collaboration has released the results of a new analysis that looks for the subtle influence of “new physics” in the production of a W boson and photon pair.    The standard model of particle physics is an incredibly successful description…

Electromagnetic interactions govern everyday life: You see an object when particles of light deposit energy on the retinas in your eyes. Our sense of touch results from the exchange of the same particles, the photons, between the atoms in our skin…

In the Standard Model of particle physics, at least one Higgs boson is needed to explain fundamental particles’ masses. There is, however, no reason why there needs to be exactly one. On the contrary, many theories of physics beyond the Standard…

CMS is presenting a wide range of results for the annual winter conference, Rencontres de Moriond. The first week of Moriond — 3–8 March — is devoted primarily to electroweak (EW) studies. Among the CMS results are further studies of the recently…

CMS has presented a rich variety of results at the Electroweak Interactions and Unified Theories sessions of the Rencontres de Moriond conference in La Thuile, Italy. Links to the Physics Analysis Summaries (PAS) from CMS made public in the last…
