Perturbative renormalization of staggered fermion operators with stout improvement: Application to the magnetic susceptibility of QCD
G. S. Bali, F. Bruckmann, M. Constantinou +5
We calculate the fermion propagator and the quark-antiquark Green's functions for a complete set of ultralocal fermion bilinears, [: scalar (S), pseudoscalar (P),…
Perturbatively improving renormalization constants
M. Constantinou, M. Costa, M. Gockeler +6
Renormalization factors relate the observables obtained on the lattice to their measured counterparts in the continuum in a suitable renormalization scheme. They have to be compute…
Perturbative renormalization functions of local operators for staggered fermions with stout improvement
M. Constantinou, M. Costa, H. Panagopoulos
In this paper we present the perturbative computation of the renormalization functions for the quark field and for a complete set of ultra-local fermion bilinears. The computation…
Perturbatively improving RI-MOM renormalization constants
M. Constantinou, M. Costa, M. Gockeler +6
The determination of renormalization factors is of crucial importance in lattice QCD. They relate the observables obtained on the lattice to their measured counterparts in the cont…
Thermodynamic properties of QCD in external magnetic fields
G. S. Bali, F. Bruckmann, M. Constantinou +8
We consider the effect of strong external electromagnetic fields on thermodynamic observables in QCD, through lattice simulations with 1+1+1 flavors of staggered quarks at physical…
