what is a CMS in particle physics?

In particle physics, a CMS (Compact Muon Solenoid) is a detector located at the Large Hadron Collider (LHC) at CERN. The CMS is a large, general-purpose detector designed to measure the properties of particles produced in high-energy proton-proton collisions at the LHC. It is one of the four main experiments at the LHC and is used to study the Higgs boson, dark matter, and other fundamental physics phenomena. The CMS detector is made up of several subsystems, including a tracking system, electromagnetic and hadron calorimeters, and a muon detection system. These subsystems work together to measure the energy, momentum, and other properties of particles produced in the collisions.
