T-odd quark distributions: QCD versus chiral models
P. V. Pobylitsa
The T-odd quark distrbutions are shown to vanish in the chiral sigma model in contrast to the opposite widespread opinion. This failure of the chiral sigma model is a feature of th…
Virtual Compton scattering in the generalized Bjorken region and positivity bounds on generalized parton distributions
P. V. Pobylitsa
The positivity bounds on generalized parton distributions are derived from the positivity properties of the absorptive part of the amplitude of the virtual Compton scattering in th…
Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena
M. J. Amarian, V. M. Braun, S. J. Brodsky +28
These are the mini-proceedings of the workshop ``Spontaneously Broken Chiral Symmetry and Hard QCD Phenomena" held at the Physikzentrum Bad Honnef from July 15 to 19, 2002. Every a…
Integral representations for nonperturbative GPDs in terms of perturbative diagrams
P. V. Pobylitsa
An integral representation is suggested for generalized parton distributions which automatically satisfies the polynomiality and positivity constraints. This representation has the…
Solution of polynomiality and positivity constraints on generalized parton distributions
P. V. Pobylitsa
An integral representation for generalized parton distributions of spin-0 hadrons is suggested, which satisfies both polynomiality and positivity constraints.
Positivity bounds on generalized parton distributions in impact parameter representation
P. V. Pobylitsa
New positivity bounds are derived for generalized (off-forward) parton distributions using the impact parameter representation. These inequalities are stable under the evolution to…
