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.
