Higher twist contributions to R-hadron phenomenology in the light gluino scenario

The open light gluino window allows non-trivial higher-twist gluino contrib utions to the proton wave function. Using a two-component model originally developed for charm hadroproduction, higher-twist intrinsic gluino contribu tions to final-state R-hadron formation are shown to enhance leading-twist production in the forward x(F) region. We calculate R-hadron production at P-lab = 800 GeV in pp, pBe, and pCu interactions with light gluino masses o f 1.2, 1.5, 3.5, and 5.0 GeV. (C) 2000 Elsevier Science B.V. All rights res erved.
