TITLE: Lattice QCD: Quantum Field Theory in Pixels & Bits

Speaker: Profa. Dra. Tereza Cristina da Rocha Mendes (IFSC/USP)

ABSTRACT: The nonlinear effects that characterize non-Abelian gauge theories such as QCD are responsible for the theory's intriguing low-energy properties, and also for the great difficulty in investigating them analytically. The lattice formulation, introduced by K. Wilson in 1974, allows the study of theory by statistical mechanics methods, such as numerical (Monte Carlo) simulation, and provides the physical limit as a controlled extrapolation. In fact, lattice QCD constitutes a first principles approach, allowing the non-perturbative investigation of the theory's low-energy properties, such as color confinement and the spontaneous breaking of chiral symmetry, which are associated with the generation of the mass of the visible universe. We will present and discuss results of this research area, describing general aspects of the formulation of gauge theories on the lattice and its numerical simulation.
