Performance of jet flavour algorithms: ML to calibrate ML in data
Very quickly after quarks are produced in proton-proton collisions, they radiate gluons (the mediators of the strong force between quarks) that in turn produce more particles that radiate gluons.

Hunting the Higgs boson siblings with top quarks
Peter Higgs and François Englert received the Nobel Prize in Physics after the 2012 discovery of the Higgs boson with a mass of 125 GeV.

Detector showers wash away backgrounds of new long-lived particles
Most searches for new physics beyond the standard model (SM) focus on particles that decay almost instantly after being produced.

Leptoquarks as intergenerational messengers
We have this idea that we communicate best within our own generation, but is this true?

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

How CMS cleaned up 85’000’000’000’000’000 bytes without touching any original, raw data!
CMS has recently conducted the largest deletion campaign in its history, deleting roughly 85 Petabytes (85’000’000’000’000’000 bytes) of data from the magnetic tapes, in order to free up space for the Run 3 collisions.

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.
