Production of π0 mesons and charged hadrons in {Mathematical expression} neon and ν neon charged current interactions

The average multiplicities of charged hadrons and of π+, π- and π0 mesons, produced in {Mathematical expression}Ne and νNe charged current interactions in the forward and backward hemispheres of the W±-nucleon center of mass system, are studied with data from BEBC. The dependence of the multiplicities on the hadronic mass (W) and on the laboratory rapidity (yLab) and the energy fraction (z) of the pion is also investigated. Special care is taken to determine the π0 multiplicity accurately. The ratio of average π multiplicities {Mathematical expression} is consistent with 1. In the backward hemisphere {Mathematical expression} is positively correlated with the charged multiplicity. This correlation, as well as differences in multiplicities between {Mathematical expression} and {Mathematical expression}, {Mathematical expression} scattering, is attributed to reinteractions inside the neon nucleus of the hadrons produced in the initial {Mathematical expression} interaction. © 1988 Springer-Verlag.
