Decay Properties of p pi- Systems Produced in Neutron Dissociation at Fermilab Energies

PDF Version Also Available for Download.

Description

The authors have examined the decay distributions of (p{pi}{sup -}) systems produced in the reaction n + p {yields} (p{pi}{sup -}) + p for neutron momenta between 120 GeV/c and 300 GeV/c. Preliminary analysis of decay moments indicates the presence of large helicity-flip amplitudes even for small (p{pi}{sup -}) mass values, and does not support the hypothesis that the helicity non-flip (p{pi}{sup -}) states are produced peripherally in impact parameter. These results are in approximate agreement with predictions of the Deck mechanism. The experiment was performed at the M-3 neutral beam of Fermilab.
