The LHCb experiment at the Large Hadron Collider (LHC, CERN) is designed to study hadron production processes and properties of hadrons containing heavy quarks (charm and beauty). The unique capabilities of LHCb—such as the high production cross-section of charm and beauty hadrons, precise reconstruction of their production and decay vertices, and reliable particle identification—enable a broad research program. This includes investigations of the hadron spectrum, observation of new (including suppressed) decay modes, studies of CP-violating processes, and searches for New Physics through the analysis of rare decays of c and b hadrons. This paper presents a review of LHCb results of studies on the physics of the charm quark.
