Renormalization constants for one-derivative fermion operators in twisted mass QCD
C. Alexandrou, M. Constantinou, T. Korzec +2
We present perturbative and non-perturbative results on the renormalization constants of the local and one-derivative vector and axial vector operators. Non-perturbative results ar…
Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions
Martha Constantinou, Petros Dimopoulos, Roberto Frezzotti +4
In this work we calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculat…
O(a^2) corrections to the propagator and bilinears of Wilson / clover fermions
Martha Constantinou, Haralambos Panagopoulos, Fotos Stylianou
We present the corrections to the fermion propagator, to second order in the lattice spacing, O(a^2), in 1-loop perturbation theory. The fermions are described by the clover action…
