Production of a0+- mesons in the reaction pp to da0+


Production of a0+- mesons in the reaction pp to da0+

Müller, H.

We investigate the reaction pp to da0 + at COSY and SIS energies together with accompanying background reactions and inclusive particle yields. The a0 + is considered as a usual quark model state with two decay channels a0 + to K+K0 and a0 + to pi+ eta. Cross sections for a0 + production as well as for the corresponding nonresonant channels pp to dK+K0 and pp to dpi+eta are compared. Especially in case of the final channel dpi+eta high statistics measurements are necessary to extract the a0 + signal from the nonresonant background.
