In this work we present, for the first time, the non-perturbative renormalization for the unpolarized, helicity and transversity quasi-PDFs, in an RI′ scheme. The proposed …
In this paper we present results for the renormalization of gauge invariant nonlocal fermion operators which contain a Wilson line, to one-loop level in lattice perturbation theory. Our …
Numerical simulation of lattice-regulated QCD has become an important source of information about strong interactions. In the last few years there has been an explosion of …
We study the leading discretization errors for staggered fermions by first constructing the continuum effective Lagrangian, including terms of O (a 2), and then constructing the …
We determine the Δ (1232) resonance parameters using lattice QCD and the Lüscher method. The resonance occurs in elastic pion-nucleon scattering with JP= 3/2+ in the …
We present results for the matrix elements of a variety of four-fermion operators calculated using quenched Wilson fermions. Our simulations are done on 170 lattices of size 32 3× 64 …
The response of the QCD vacuum to a constant external (electro) magnetic field is studied through<? format?> the tensor polarization of the chiral condensate and the magnetic …
In this paper we present one-loop results for the renormalization of nonlocal quark bilinear operators, containing a staple-shaped Wilson line, in both continuum and lattice …

In this work we calculate the renormalization of counterterms which arise in the lattice action of $ N= 1$ Supersymmetric QCD (SQCD). In particular, the fine-tunings for quartic couplings …
