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…
BK-parameter from Nf = 2 twisted mass lattice QCD
ETM Collaboration, M. Constantinou, P. Dimopoulos +12
We present an unquenched lattice computation of the parameter which controls oscillations. A partially quenched setup is employed with two maximally…
Two-loop renormalization of fermion bilinear operators on the lattice
A. Skouroupathis, H. Panagopoulos
We compute the renormalization functions on the lattice, in the RI' scheme, of local bilinear quark operators , where . This calculation…
O(a^2) corrections to 1-loop matrix elements of 4-fermion operators with improved fermion/gluon actions
Martha Constantinou, Vittorio Lubicz, Haralambos Panagopoulos +2
We calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. The novel aspect of our calculations is that they are…
