Intranuclear Cascade in the Interactions of Neutrinos with Neon Nuclei.

A method is developed for separating vN interactions from interactions involving an intranuclear cascade in vNe scattering at a mean neutrino energy of 145 GeV. The fraction of events featuring a cascade is evaluated by using a sample of vNe charged-current interactions. It is found that the multiplicity of charged particles in the forward direction takes the same value for events with and without a cascade for 4 < W² < 550 GeV². In the backward direction, cascade events have the charge multiplicity higher than the multiplicity for cascade-free events by 2.36 units. It is found that particles with momenta less than 2 GeV/c make a dominant contribution to the rescattering process. A depletion of the fastest particles for W² < 50 GeV² is observed, in accord with the formation-time concept. [ABSTRACT FROM AUTHOR]
