摘要：

Sigma(+)p elastic scattering has been studied using a scintillating fiber block (SCIFI) which served as a target for the production of Sigma(+) hyperons as well as for subsequent Sigma(+) scattering on hydrogen. A new technique for the analysis of the hyperon-nucleon scattering in the SCIFI has been developed and established. In this paper, Sigma(+)p elastic scattering events have been identified in the Sigma(+) momentum range of 300-600 MeV/c, and differential cross sections have been obtained at two angles. The results are compared with various theoretical baryon-baryon interaction models. (C) 1999 Elsevier Science B.V.
