Virtual diffraction and the reaction $$K^ - p \to \bar K^{*0} \pi ^ - p$$

Abstract

Detailed calculations of the «Deck» virtual diffraction background plus possible coherent diffractively produced resonances and the incoherent K N /* resonance are presented at 6 and 10 GeV/c for the reaction\(K^ - p \to \bar K^{*0} \pi ^ - p\). «Off-shell» and «absorption» effects have been allowed for by the inclusion of phenomenological form factors. A simple parametrization for the diffractive production of the resonances in the K*π enhancement is employed and these amplitudes, which include the subsequent decay, interfere with the «Deck» background. A reasonable fit to experiment is obtained.
