Abstract

The inclusive reactions p¯n→π+X, 2π+X have been studied at 3.5 GeV/c in a bubble-chamber experiment. In the absence of high-energy data, no test of scaling was performed; however, the longitudinal- and transverse-momentum distributions are qualitatively similar to other "exotic" reactions at medium-high energies (12-24 GeV). To facilitate compilations the data have been parametrized empirically in terms of x and pT. The two-particle longitudinal-momentum distributions also show familiar behavior, and a strong positive correlation appears at xc≃xd≃0. The π+ energy distribution agrees remarkably well with simple thermodynamic functions, but our statistics do not allow us to distinguish between Boltzmann and Bose-Einstein forms.
