Study of Sigma /sup +or-/(1385) inclusive production in K/sup -/p interactions at 42 GeV/c

Properties of Sigma /sup +or-/(1385) inclusively produced in 4.2 GeV/c K/sup -/p interactions are studied. Inclusive cross sections are presented together with differential cross sections as functions of x and p/sub t//sup 2/ for both Sigma /sup +/(1385) and Sigma /sup - /(1385). The complete densit...

Descripción
Sumario:Properties of Sigma /sup +or-/(1385) inclusively produced in 4.2 GeV/c K/sup -/p interactions are studied. Inclusive cross sections are presented together with differential cross sections as functions of x and p/sub t//sup 2/ for both Sigma /sup +/(1385) and Sigma /sup - /(1385). The complete density matrix for Sigma /sup +/(1385) production at small momentum transfer is studied as a function of t and of recoil mass MM/sup 2/. Substantial agreement with the predictions of the additive quark model is found. The Sigma /sup + /(1385) production in the target fragmentation region is studied in the framework of the triple-Regge model. (17 refs).
