The LHCb (standing for "Large Hadron Collider beauty") experiment is one of the particle physics detector experiments collecting data at the Large Hadron Collider accelerator at CERN. LHCb is a specialized b-physics experiment, that is measuring the parameters of CP violation in the interactions of b-hadrons (heavy particles containing a bottom quark). Such studies can help to explain the Matter-Antimatter asymmetry of the Universe.
The detector is also able to perform measurements of production cross sections and electroweak physics in the forward region. Approximately 840 people from 60 scientific institutes, representing 16 countries, form the collaboration which built and operate the detector.. The experiment is located at point 8 on the LHC tunnel close to Ferney-Voltaire, France just over the border from Geneva. The (small) MoEDAL experiment shares the same cavern.
