Search for New Physics with one charged lepton and missing energy
Experimental evidence from the last half-century has established the standard model as a foundational theory of particle physics.

One, two, three, W bosons bloom in the spring
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 of radioactivity and an essential ingredient to our Sun’s thermonuclear process.

Hadron Calorimeter Next-Generation Clock Control Module Rework
Around the one-year anniversary of the first COVID-19 lockdown in Switzerland, physicists and engineers working on the Compact Muon Solenoid (CMS) experiment closed the case on an elusive problem affecting the operation of the Hadron Calorimeter (HCAL) detector.

Low-energy leptons for high-energy physics
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.

“To be, or not to be conserved, that is the question”: Lepton flavor in Higgs boson decays
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.

Searching for new physics with very high energy lepton pairs
Are there more fundamental particles than the ones we currently know?
-
Searching for a hidden signal
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.

Jetting through a droplet of matter from the early universe
High energy heavy-ion collisions provide a unique opportunity to study one of the four forces of nature, the strong force, under extreme conditions.

The top quarks’ energetic light
Electromagnetic interactions govern everyday life: You see an object when particles of light deposit energy on the retinas in your eyes.
