Abstract:

We perform a momentum-space calculation of the reaction

pp \rightarrow pp\pi ~0

near threshold. Direct production and pion rescattering are taken into account. For the latter a T-matrix obtained from a microscopic model of the

\pi N

interaction is employed. The effects of some approximations commonly used in studies of

pp \rightarrow pp\pi ~0

\ are discussed. We find that those approximations overestimate the cross section and also modify its energy dependence. We obtain a significant contribution from rescattering, but not nearly enough to describe the data.
