Abstract
The inclusive production of the resonance in collisions at 147 GeV/c has been studied. The is found to be produced in comparable amounts in four-, six-, eight-, and ten-prong events. The Feynman-, , , and the decay angular distributions of the are found to be consistent with the predictions of a one-pion-exchange model with absorption. Essentially all of the are found to be associated with a low-mass enhancement. The cross section is approximately constant from 11 to 205 GeV/c, which could indicate that the is a decay product of a target-fragmentation object. While the one-pion-exchange character of the production and the target-fragmentation character of the low-mass enhancement can both be described in terms of a Deck-type diagram, a Monte Carlo study indicates that any mechanism that produces particles with limited transverse momentum will yield a low-mass enhancement.
