Abstract [en]

Lattice QCD provides a framework for performing numerical simulations of quantum

chromodynamics. In lattice QCD—as a step towards obtaining quantities which can

be compared with experiment—it is in general necessary to determine

renormalization factors for the operators being studied. In this master thesis, the

renormalization factors for several local operators are determined non-perturbatively

in lattice QCD, by utilizing the RI'–MOM scheme. Numerical simulations are

performed for a wide range of quark masses which allow for the chiral limit to be

taken. As an essential step in the calculation, a subtraction of leading lattice artifacts is

performed by utilizing (boosted) lattice perturbation theory at one loop. The final

renormalization factors are presented in the RGI scheme, for several values of the

inverse coupling: ß = 5.20, 5.30 and 5.50.
