Longitudinal Phase Space (LPS) Analysis of the Interaction np Yields pp pi sup - at Psub(N)=3-5 GeV/C

摘要

The reaction np yields pp pi sup - is analyzed at Psub(n)=5.10 and 3.83 GeV/c using longitudinal phase space (LPS) analysis. The distributions of omega (Van Hove's angle) along with the hexagonal plots are investigated in detail. From the omega -distributions it is possible to conclude that, whenever allowed, the diffractive mechanism (Pomeron exchange) dominates the three-body final state. For the first time the approximate percentage, on the basis of hexagonal distributions, of the different processes involved (diffractive, peripheral, etc.) is calculated which may very well agree with the expectations at these energies. The investigation has been performed at the Laboratory of High Energies, Laboratory of Computing Techniques and Automation, JINR, Dubna and Laboratory of Nuclear Physics, University of Bucharest.
