The Cornell Potential is a effective method to account for the confinement of quarks. It was developedin the 1970s to explain the masses of quarkonium states and account for the relation between the mass and angular momentum of the hadron (the so-called Regge trajectories). The potential has the form: where is the effective radius of the quarkonium state, is the QCD running coupling, is the QCD string tension and GeV is a constant. Initially, and where merely empirical parameters but with the development of QCD can now be calculated using perturbative QCD and Lattice QCD, respectively.
