Abstract:

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.

Abstract:

A measurement of the direct production of photons with high transverse momentum from {Mathematical expression} collisions at {Mathematical expression} GeV is presented. The structure of events containing a high transverse momentum photon is studied. The results support predictions from QCD theory. © 1988 Springer-Verlag.
