We discuss a general framework for the evaluation of the gluonic form factors in light
hadrons at low momentum transfer, in the QCD instanton vacuum. At medium resolution of …

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 …

This work is a continuation in our series of papers that addresses quark models of hadronic
structure on the light front, motivated by the QCD vacuum structure and lattice results. In this …

We use the QCD instanton vacuum model to discuss the emergence of the light scalar and
vector mesons on the light front. We take into account both the instanton and anti-instanton …

We analyze the photoproduction of η c, b off a proton in the threshold region, in terms of C-
odd gluonic correlations in the off-forward proton matrix element. Near threshold, the …

The existing theory of hard exclusive QCD processes is based on two assumptions:(i)
factorization into a hard block convoluted with the light front distribution amplitudes;(ii) use of …

The precise quark mass dependence of the one-loop effective action in an instanton
background has recently been computed [Phys. Rev. Lett. 94, 072001 (2005). PRLTAO …

We study violation of quark-hadron duality for B¯→ X ul ν and D→ X dl ν decays in the
presence of the right-handed current operator. For this case, we show that duality violation …

We study the Sivers function for valence u and d quarks in the proton within the instanton
model for QCD vacuum, adopting the MIT bag model wave functions for quarks. Within …

We discuss a nonperturbative mechanism for the single-spin asymmetries in the strong
interaction. This mechanism is based on the existence of a large anomalous quark …
