Room for an S = +1 pentaquark in K+ - nucleus phenomenology
A. Gal, E. Friedman
Abstract
Evidence for excitation of exotic S=+1 pentaquark degrees of freedom is presented by studying optical-potential fits to K+ - nucleus total, reaction and elastic-differential cross section data at p(lab) = 500 - 700 MeV/c. Estimates of the underlying two-nucleon absorption K+ n N --> Theta+ N reaction cross section are made and are used for discussing the anticipated cross section of the strangeness exchange reaction K+ N --> pi Theta+.
