Modeling Nucleon Generalized Parton Distributions
Abstract
We discuss building models for nucleon generalized parton distributions (GPDs) H and E that are based on the formalism of double distributions (DDs). We found that the usual "DD+D-term" construction should be amended by an extra term, E1+(x,) built from the α/β moment of the DD e(β,α) that generates GPD E(x,). Unlike the D-term, this function has support in the whole -1 ≤ x ≤ 1 region, and in general does not vanish at the border points |x|=.
