The Higgs boson, as it intracts with itself
The Higgs boson plays a crucial role in the standard model of particle physics.

Disclosing quantum corrections to electromagnetic interactions of tau leptons
In quantum electrodynamics (QED), the quantum theory of electromagnetic interactions, the magnetic dipole moment of a particle acquires quantum corrections originating from interactions with virtual photons and other particles, often referred to as the anomalous magnetic moment of that particle.

A dark world ruled by a strong force
Above: Event display for a potential SUEP event, recorded at CMS in 2018, showing the characteristically high multiplicity of soft tracks in yellow.

Using Machine Learning to find good muons
The CMS experiment at the LHC is set to explore the fundamental nature of our universe.

Flavoured Mysteries: searching for the tau lepton’s 3 muon decay
It was 1918 when the mathematician Emmy Noether published what is known as her most famous theorem, revealing the fundamental relation between the symmetries of a physical system and the laws enforcing the conservation of some of its characteristic quantities.

Three is a charm!
Three-jet event with an invariant mass of 7.2 TeV, showing the jets (yellow cones) and the energy deposited in the electromagnetic (green) and hadron (blue) calorimeters.

What if there was a second and lighter Higgs boson?
In 2012, the ATLAS and CMS Collaborations observed a new boson with a mass of 125 GeV, whose properties are compatible with those of the Higgs boson predicted by the Standard Model (SM) of particle physics.

A Step Deeper into Elementary Particle Interactions with ZZ+jets
The CMS Collaboration has recently reported a new study of ZZ+jets production, a process described by the Standard Model of particle physics.

LHC experiments see first evidence for rare Higgs boson decay into two different bosons
The discovery of the Higgs boson in 2012 marked a significant milestone in particle physics.

Muons meet beauty and the strange at CMS
The standard model (SM) of particle physics is by far the most successful theory describing the experimental observations of particle interactions.
