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 …

This is the first of a sequence of papers that addresses the nonperturbative origin of the
central and spin-dependent forces between quarks. Its main thrust is a focus on meson …

We revisit the problem of dipole-dipole scattering via exchanges of soft Pomerons in the
context of holographic QCD. We show that a single closed string exchange contribution to …

Van der Waals interactions between two neutral but polarizable systems at a separation R
much larger than the typical size of the systems are at the core of a broad sweep of …

A bstract The nonperturbative approach to soft high-energy hadron-hadron scattering, based
on the analytic continuation of Wilson-loop correlation functions from Euclidean to …

We revisit the effects of QCD instantons in semi-inclusive deep inelastic scattering. We show
that large single spin asymmetry (SSA) effects can be induced in longitudinally and …

A bstract We show how to obtain the leading energy dependence of hadronic total cross
sections, in the framework of the nonperturbative approach to soft high-energy scattering …

We review some aspects of spin physics where QCD instantons play an important role. In
particular, their large contributions in semi-inclusive deep-inelastic scattering and polarized …

Using the AdS/CFT correspondence, we study the high-energy behavior of colorless dipole
elastic scattering amplitudes in\(\mathcal {N}= 4\) SYM gauge theory through the Wilson loop …

We use AdS/QCD to analyze the quark and gluon scalar and pseudoscalar condensates
around static color sources described by a circular Wilson loop. We also derive the static …
