Unveiling the tWZ process: where no one has ever looked before
In the thrilling world of particle physics, our mission at the Large Hadron Collider (LHC) is to explore the mysteries of the universe by conducting experiments and pushing the boundaries of the Standard Model (SM).

Using top quarks to probe nature’s secrets
The standard model of particle physics (SM) is one of the most precise theories ever conceived, capable of predicting certain quantities with up to 14 digits of precision.

CMS observes four-top quark production
CMS observed the simultaneous production of four top quarks, one of the rarest physics processes ever observed at the LHC, opening the door to detailed searches for physics beyond the Standard Model (SM).

A new way to produce top quarks
The CMS collaboration has seen evidence of a rare mechanism to produce four top quarks.

Top quarks fast to arrive at new energy frontier
On 5 July 2022, the LHC surpassed the previous energy limits of experimental particle physics, breaking its own record by achieving stable proton-proton collisions at a center-of-mass energy of √s = 13.6 TeV.

Symmetric or not? That’s the question!
The heaviest known particle, the top quark, is one of our main gateways to search for new phenomena that are not addressed by our existing knowledge, the standard model of particle physics (SM), either through precision measurements of the top quark’s properties or by considering it as a decay product of (never seen before) heavier…

Jet cones with top flavour
CMS has developed a new method to measure the properties of the top quark with high precision.

Precision measurements using top quarks at CMS
Amongst all known elementary particles, the top quark is peculiar: weighing as much as a Tungsten atom, it completes the so-called 3rd generation of quarks and is the only quark whose properties can be directly measured.

Measurement of the t-channel single Top-quark production rates in pp collisions at 7 TeV
The Top quark is the heaviest of the six quarks of the Standard Model and was discovered only 16 years ago by the Tevatron experiments at Fermilab.
