Lattice field theory applications in high energy physics

Abstract

Lattice gauge theory was formulated by Kenneth Wilson in 1974. In the ensuing decades, improvements in actions, algorithms, and computers have enabled tremendous progress in QCD, to the point where lattice calculations can yield sub-percent level precision for some quantities. Beyond QCD, lattice methods are being used to explore possible beyond the standard model (BSM) theories of dynamical symmetry breaking and supersymmetry. We survey progress in extracting information about the parameters of the standard model by confronting lattice calculations with experimental results and searching for evidence of BSM effects.Comment: 8 pages, 5 figures, to appear in the Proceedings of the XXVII IUPAP Conference on Computational Physics (CCP2015), Indian Institute of Technology Guwahati, Assam, India, published in Journal of Physics: Conference Series (JPCS), published by IO
