The generalized parton distributions, introduced nearly a decade ago, have emerged as a
universal tool to describe hadrons in terms of quark and gluonic degrees of freedom. They …

The main ideas, methods and results in the investigation of the asymptotic behaviour of
exclusive processes are reviewed. We discuss power behaviour and its dependence on …

We develop some new techniques extending the standard QCD sum-rules approach to
hadron properties in alternating external fields. The string operator expansion in …

Recently, there have been some interesting developments involving off-forward parton
distributions of the nucleon, deeply virtual Compton scattering, and hard diffractive vector …

In this paper we discuss decays of the Higgs boson to quarkonia in association with a
photon. We identify a new mechanism for producing such final states in Higgs decays that …

Due to the momentum transfer r≡ p− p′ from the initial proton to the final, the “asymmetric”
matrix element〈 p′| G… G| p〉 that appears in the pQCD description of hard diffractive …

Magnetic moments of a proton and a neutron are calculated in the QCD sum rule approach.
The substantial role of the external electromagnetic field induced vacuum expectation …

The Lagrangian of Quantum Chromodynamics is invariant under conformal transformations.
Although this symmetry is broken by quantum corrections, it has important consequences for …

A bstract We present a detailed analysis of the rare exclusive Higgs boson decays into a
single vector meson and a photon and investigate the possibility of using these processes to …

We review the recent status of the QCD sum rule approach to study the properties of
hadrons in vacuum and in hot or dense matter. Special focus is laid on the progress made in …
