Lattice QCD, the strong coupling constant and heavy quark potentials
QCD is the theory which describes the interaction between quarks and gluons. QCD is able to explain a large number of high energy phenomenological data relying on the perturbative approach to Quantum Field Theory. However, perturbation theory cannot explain all particle phenomena. In particular, the question of quark confinement and chiral symmetry breaking. Lattice QCD (LQCD) is a first principles approach to QCD which can handle both the high energy (perturbative) and the low energy (nonperturbative) regimes. IN this project we aim to use LQCD, in the quenched approximation, to measure the strong coupling constant in the Landau gauge, to measure and model the interaction between heavy quarks and heavy quarks and gluons.
