Clocking nature’s heaviest elementary particle: Do top quarks play by Einstein’s rules the whole day and night?
In a first measurement of its kind at the LHC, the CMS experiment tests whether top quarks adhere to Einstein’s special theory of relativity, and improves the bounds on noncompliance by up to a factor of one hundred with respect to previous results.

Nailing down the invisible
Top quarks are the heaviest known elementary particles, as heavy as a tungsten atom.

“Spooky action at a distance” between the heaviest particles
Recently, and about two decades after the first solid proof of entanglement between two photons by Anton Zeilinger and his team, the ATLAS and CMS experiments reported the observation of quantum entanglement between the top quark and its antiparticle simultaneously produced at rest at the LHC.

Top quarks follow expectations at 5 TeV
Following its mission to address fundamental questions about Nature, the Large Hadron Collider (LHC) has operated at different center-of-mass energies, colliding protons and/or heavy ions.

A rich collection of top quark mass measurements by the CMS experiment
When it comes to top quark mass measurements, the CMS collaboration has the largest and most complete collection of publication-quality results, covering a wide range of methods and approaches.

Entangled Titans: unraveling the mysteries of Quantum Mechanics with top quarks
The CMS experiment has just reported the observation of quantum entanglement between a top quark and a top antiquark, simultaneously produced at the LHC.

Not quite single at 13.6 TeV: top quark comes in association with a W boson
Back in September 2022, four months after the start of the LHC Run 3, the CMS collaboration released the first measurement using data at the new collision energy of 13.6 TeV.

A novel trail: simultaneous probe of rare top quark events
Even after almost 30 years since its discovery, the top quark is still offering unprecedented opportunities to improve our understanding of nature.
