Abstract

The semiclassical distorted wave model is developed to describe (π ^-, K⁺) inclusive spectra related to ∑^- formation measured at KEK with p_π = 1.2 GeV/c. The shape and magnitude of the spectrum obtained with a ²⁸Si target are satisfactorily reproduced using a repulsive ∑-nucleus potential whose strength is of the order of 30-50 MeV. This strength is not as large as the value of more than 100 MeV obtained using the estimation presented in the report of the experiment.
