The reaction pp→πd is studied in a relativistic meson rescattering model. For 1.3<Tp<2.4 GeV the differential cross section and the asymmetry are calculated and compared to experiment. The model introduces simple form factors for the leading πN partial waves which depend on the virtuality of the exchanged mesons, π and ρ. All remaining input is derived from experimental constraints. The data can be described by energy-independent form factors. The asymmetries are sensitive to pp distortion factors and further details of the model.
