Using machine learning to improve the detection of new physics in the interactions of the top quark
Using machine learning to improve the detection of new physics in the interactions of the top quark Although our theory describing the interactions between fundamental particles is exceptionally successful, it has weaknesses.

Exploring the physics processes inside the hottest matter in the universe
Quarks are elementary particles in the Standard Model and the building blocks of the protons and neutrons in atoms.

Illuminating! Counting LHC collisions with CMS
In the LHC, groups of 100 billion protons collide 25 million times every second.

Scrutinizing production and decay kinematics of the Higgs boson using its golden decay channel
The CMS collaboration has submitted a paper with a new, precise analysis of the data enriched in the Higgs boson decays to four leptons.

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.

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?
