Experimental evidence from the last half-century has established the standard model as a foundational theory of particle physics. Still, it is clear that the standard model is not the final theory. There are many open questions: Is the mass of Higgs natural or fine-tuned?
The Standard Model of the fundamental particles describes the W and Z bosons as the mediator particles of the weak force, one of the four known fundamental forces responsible for the phenomenon
Around the one-year anniversary of the firs
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 new symmetry of nature, which im
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 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.
High energy heavy-ion collisions provide a unique opportunity to study one of the four forces of nature, the strong force, under extreme conditions.
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 and the objects we touch.
In the Standard Model of particle physics, at least one Higgs boson
