Does the behaviour of the Higgs boson match the expectations?
The standard model of particle physics is our current best theory to describe the most basic building blocks of the universe, the elementary particles, and the interactions among them.

LHC as the vector boson collider
After the Higgs boson discovery in the year 2012, the standard model of particle physics offers a complete and consistent description of elementary particle interactions that, despite the many attempts, has not been falsified by experimental evidence to date. Nevertheless, several hints indicate that a new more comprehensive theory that includes and extends it may…

A new window into the shadow world: exotic particle decays in the muon detectors
As physicists seek the elusive particles that may reveal a new understanding of the universe’s inner workings, one intriguing possibility is the conceivable existence of new particles that live in a shadow universe, called the “dark sector.”

Live long and prosper: Searching for the long-lived relatives of the Higgs boson
A recent result from CMS searches for long-lived particles through the so-called “Higgs portal” in ways never done before.

Any more Higgses we should know about?
This year marked the ninth anniversary of the discovery of the Higgs boson; the Standard Model particle linked to the mystery of creating the mass of all the other fundamental particles through the so-called Higgs mechanism.

Searching for the Dark Side of the Universe
Could you imagine what the dark part of the universe is like?

The Four Beauties in the Tale of two Higgses
The interaction of the Higgs boson with its own field leads to its mass generation.

Trio of J/ψ particles in one go
High-energy particle accelerators are unique tools to study the structure of matter at the shortest distances.

Jets-of-all-trades: constraining Standard Model and Beyond
For the first time, CMS physicists extract the fundamental parameters of QCD together with constraints on the New Physics.

A tale of two colliders and the unrivalled precision on the Z invisible width
The most powerful particle collider in the world, the Large Hadron Collider (LHC), was built in the 27 km tunnel originally excavated for the highest energy electron-positron collider ever built, LEP.
