Lattice perturbation theory in the overlap formulation for the Yukawa and gauge interactions

Abstract

Lattice perturbation theory is discussed in the overlap formulation for the Yukawa and gauge interactions. One and two point functions are studied for fermion, scalar and gauge fields, taking the Standard Model as an example. The formulae for the self-energies are given from which their divergent and finite parts can be computed at the one loop level.
