Renormalization of Flavor Singlet and Nonsinglet Fermion Bilinear Operators
M. Constantinou, M. Hadjiantonis, H. Panagopoulos
We compute the difference in the renormalization of flavor singlet and nonsinglet fermion bilinear operators, to two loops in perturbation theory. Our results are applicable to a r…

Topological charge renormalization: A test case for 3-loop vacuum calculations using overlap fermions and Symanzik improved gluons
A. Skouroupathis, H. Panagopoulos
We calculate perturbative renormalization properties of the topological charge, using the standard lattice discretization given by a product of twisted plaquettes. We use the overl…

Lambda-parameter of lattice QCD with the overlap-Dirac operator
C. Alexandrou, H. Panagopoulos, E. Vicari
We compute the ratio between the scale parameter , associated with a lattice formulation of QCD using the overlap-Dirac operator, and of the…
