abstract = {Existing pion+nucleus Drell-Yan and electron+pion scattering data are used to develop ensembles of model-independent representations of the pion generalised parton distribution (GPD). Therewith, one arrives at a data-driven prediction for the pion mass distribution form factor, θ2. Compared with the pion elastic electromagnetic form factor, θ2 is harder: the ratio of the radii derived from these two form factors is rθ2π/rπ=0.79(3). Our data-driven predictions for the pion GPD, related form factors and distributions should serve as valuable constraints on theories of pion structure.},
