A primary goal of the Large Hadron Collider (LHC) is to hunt for evidence of beyond the Standard Model (BSM) dynamics through deviations from the Standard Model (SM) predictions. If the mass of BSM particles exceeds the energy accessible in…
In the world of elementary particles, there are twelve generic types of fermions (spin ½ particles): 3 up-type quarks, 3 down-type quarks, 3 charged leptons, and 3 neutrinos. They come in three generations. The number “3” is really a magic…
The completion of the standard model (SM) with the discovery of the Higgs boson stands as a resounding success in the world of particle physics. However, significant questions remain unanswered, such as the nature of dark matter (DM), and the…
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…
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…
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…
Cosmological observations tell us that Dark Matter makes up roughly 80% of all the matter in the Universe. However, no Dark Matter particle has ever been observed. To verify whether it can be produced in the laboratory, the CMS Collaboration at the…
A new CMS paper describes how the CMS experiment can squeeze more physics out of the LHC data by using smarter data selection/reduction techniques.
The Large Hadron Collider produces an avalanche of data; the beams collide 40 million times per…
One of the events determined by the AI algorithm to be highly anomalous and therefore potentially coming from a new particle. The central jet shows particles clustered around two different cores within the cone, a configuration distinct from a…
Event display for a potential SUEP event, recorded at CMS in 2018, showing the characteristically high multiplicity of soft tracks in yellow.
Could there be a “dark world“ composed of invisible particles held together by a new strong dark force,…
The main goal of the LHC physics programme is to deeply understand the fundamental principles of particles and their interactions. As part of this quest, physicists are searching for evidence of new particles, which would potentially confirm the…
Imagine diving into the very core of the universe, where the tiniest pieces that make up everything hold the answers to big cosmic questions. Leading this exciting journey is the CMS team at the Large Hadron Collider (LHC). We are on a mission to…
