DELPHI experiment

The DELPHI (DEtector with Lepton, Photon and Hadron Identification) experiment was one of the major particle physics experiments at the Large Electron-Positron Collider (LEP) at CERN, which operated from 1989 to 2000. The LEP accelerator provided high-energy electron-positron collisions, allowing physicists to study a variety of processes and phenomena related to the Standard Model of particle physics.
