Disentangling positivity constraints for generalized parton distributions
arXiv:hep-ph/0201030 · doi:10.1103/PhysRevD.65.114015
Abstract
Positivity constraints are derived for the generalized parton distributions (GPDs) of spin-1/2 hadrons. The analysis covers the full set of eight twist-2 GPDs. Several new inequalities are obtained which constrain GPDs by various combinations of usual (forward) unpolarized and polarized parton distributions including the transversity distribution.
