Production of a+0-Mesons in the Production of a+0-Mesons in the Reaction pp ® da+0
Production of a+0-Mesons in the Production of a+0-Mesons in the Reaction pp ® da+0
Müller, H.
Abstract
We investigate the reaction pp ® 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
+
® K+[`(K0)] and
Cross sections for a0
+ production as well as for the corresponding nonresonant channels
pp ® dK+[` (K0)] and pp
Especially in case of the final channel dp +
h
high statistics measurements are necessary to extract the a0
+ signal from the nonresonant background.
