STUDY OF GREY PARTICLES IN HIGH-ENERGY HADRON-NUCLEU AND NEUTRINO-NUCLEUS INTERACTIONS

Abstract

The present work is an inclusive study of the grey particle production in the hadron- nucleus and the charged-current neutrino-nucleus interactions at high incident energies. Grey particles which are mostly protons in the energy range 30-400 MeV arise from the intranuclear cascade initiated by the passage of the incident hadron (or the incident neutrino) inside the target. The mathematical procedure proposed here is based on the main assumption that the grey particles are emitted only from the first two generations of the cascade. Higher generations are considered to contribute only to slow evaporated particles (such as protons with energy less than 30 MeV) and therefore they will not be taken into account. This main assumption . is introduced in this work in order to investigate two different aspects in two parts. In part I the production of grey particles in hadron-nucleus interactions
