Empirical Determination of the Pion Mass Distribution

Existing pion+nucleus Drell-Yan and electron+pion scattering data are used to develop ensembles of model-independent representations of the pion generalized parton distribution (GPD). Therewith, one arrives at a data-driven prediction for the pion mass distribution form factor, ?2p

Automated summary

Ensembles of model-independent representations of the pion generalized parton distribution (GPD) are developed using existing pion+nucleus Drell-Yan and electron+pion scattering data. This leads to a data-driven prediction for the pion mass distribution form factor, ?2p.
