The discovery of the Higgs boson represents a significant breakthrough in understanding the universe’s fundamental structure and dynamics. Despite this achievement, numerous profound mysteries persist, namely what is the nature of dark matter, why…

CMS has released 12 new results for the spring conferences (LHCP 2024, SQM 2024, and SUSY24), spanning its entire physics program: - Studying high momentum top quark-antiquark pairs, we have observed, for the first time, entanglement between top…

  Did you know that every second more than 100 trillion tiny particles called neutrinos pass through your body without causing any harm? These mysterious particles are produced abundantly throughout the universe in events like nuclear reactions in…

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…

    It might have occurred to you to look with curiosity at your present the day of your birthday. Wrapped in colorful paper, a surprise was waiting for you. You might be the kind of person who rushes to remove the packaging to see what’s inside. Or…

The recent results from the Muon g-2 Collaboration have added to the growing tension between the measured and predicted values of the muon’s magnetic moment. The equivalent measurement of this property for the electron is a cornerstone of quantum…

The first wafers of the CMS Read Out Chip (CROC) for the High Luminosity Pixel detector have been produced and tested, marking a major milestone for the next generation CMS Tracker. Each silicon wafer contains 136 chips that are built to withstand…

  New in! CMS physicists search for heavy cousins of the neutrino in beauty meson decays Back in 2018, the physicists of the CMS experiment designed and recorded a B-meson-enriched data sample, the “B-Parking” data set. The B mesons (short for…

When we look at ourselves in a mirror, we see a virtual twin, identical but with left and right inverted. Charge-parity (CP) is the equivalent of a mirror for fundamental particles. If the symmetry was respected in nature, each particle would see a…

From time to time, we need to take our cars in for a checkup to make sure everything is up to speed, and here we check up on how well our CMS detector is working. The CMS detector is one of the main detectors at the Large Hadron Collider (LHC) at…

How an evacuation of the CMS experimental cavern has provided invaluable human behaviour data to improve the emergency preparedness for complex underground facilities. CERN and CMS strive for excellence in safety matters, with a commitment to…

As a next step towards more open access to science, the CMS collaboration has just released in electronic format a set of likelihood functions describing early measurements of the Higgs boson. The full statistical model and the data used to make the…
