On the A-dependence of nuclear generalized parton distributions
V. Guzey, M. Siddikov
We perform a microscopic evaluation of nuclear GPDs for spin-0 nuclei in the framework of the Walecka model. We demonstrate that the meson (non-nucleon) degrees of freedom dramatic…
Analyticity properties of three-point functions in QCD beyond leading order
A. P. Bakulev, A. I. Karanikas, N. G. Stefanis
The removal of unphysical singularities in the perturbatively calculable part of the pion form factor--a classic example of a three-point function in QCD--is discussed. Different `…
Magnetic susceptibility of the QCD vacuum
Hyun-Chul Kim, M. Musakhanov, M. Siddikov
We investigate the magnetic susceptibility of the QCD vacuum, based on the instanton vacuum. Starting from the instanton liquid model for the instanton vacuum, we derive the light-…
Pion form factor analysis using NLO analytic perturbation theory
N. G. Stefanis
I present results for the pion's electromagnetic form factor in the spacelike region, which implement the most advanced perturbative information currently available for this observ…
Transversity distribution function in hard scattering of polarized protons and antiprotons in the PAX experiment
A. V. Efremov, K. Goeke, P. Schweitzer
Estimates are given for the double spin asymmetry in lepton pair production from collisions of transversely polarized protons and antiprotons for the kinematics of the recently pro…
Extraction of the pion-nucleon sigma-term from the spectrum of exotic baryons
P. Schweitzer
The pion nucleon sigma-term is extracted on the basis of the soliton picture of the nucleon from the mass spectrum of usual and the recently observed exotic baryons, assuming that…
