Abstract: We present analytical results for the Euclidean 2-point correlator of the flavor- singlet vector current evolved by the gradient flow at next-to-leading order $$ \left(\mathcal{O}\left({g}^2\right)\right) $$ in perturbatively massless QCD-like theories. We show that the… read more here.

Abstract: We study the vector and axial-vector current correlators in perturbative and non-perturbative regimes of QCD. The correlators in Euclidean coordinate space are calculated on the lattice using the Mobius domain-wall fermion formulation at three lattice… read more here.

DOI: 10.1134/s1063778819040069
Abstract: New expressions for components of the form factor for a composite system of two equal-mass relativistic fermions were obtained for the vector-current case. The respective consideration was performed within the relativistic quasipotential approach based on… read more here.
