The Reaction pi- p --> omega N at Momenta from 20-GeV/c to 200-GeV/c

The reaction π−p→ωn in the beam-momentum range from 20 to 200 GeV/c has been studied using data acquired at Fermilab. In this Letter, the integral and differential cross sections for this reaction are presented. The integral cross sections are considerably larger than those previously reported. The differential cross sections can be reproduced quite easily by Regge models. As predicted by such models, natural-parity exchange dominates production throughout this energy region.

Pion Charge Exchange Scattering at High-Energies

We report on a study of pion charge-exchange scattering carried out at Fermilab in the energy range 20 to 200 GeV. The results can be described remarkably well by a simple Regge-pole model. The charge-exchange cross sections in the forward direction lead to a prediction for the difference in total cross sections of π−p and π+p which is in satisfactory agreement with direct measurements of this difference in another experiment at Fermilab.

The Reaction pi- p ---> eta n at High-Energies

Measurements on the reaction π−p→ηn have been carried out at Fermilab with beam energies from 20 to 200 GeV in the same experiment in which pion charge-exchange scattering was studied. The differential cross sections have a pronounced dip in the forward direction. The data can be described well by a simple Regge-pole model but the resulting A2 trajectory is not degenerate with the ρ trajectory extracted from the charge-exchange data.

Reaction $\pi^- p \to \eta n$ in the 15-{GeV}/$c$ to 40-{GeV}/$c$ Momentum Range

A high-statistics measurement of the reaction π − p→ η n; η →2 γ has been performed at the 70 GeV Serpukhov accelerator for 15, 20, 25, 30 and 40 GeV/ c incident pion momentum using the NICE set-up with its associated 648-channel hodoscope spectrometer for γ-ray detection. It is found that the spin-flip and non-spin-flip amplitudes can be parametrized, for small | t |, as exponentials with the same slopes to within a few percent. For | t | ≳ 1 (GeV/ c ) 2 there is a break in the differential cross section. In addition, the A 2 effective trajectory deviates markedly for | t | ≳ 1 GeV/ c ) 2 from the linear behaviour valid for smaller | t |.

INVESTIGATION OF THE CHARGE EXCHANGE REACTION H-3 p ---> He-3 n AT 2.5-GeV/c TRITON MOMENTUM

The differential cross sections d sigma /dt of the reactions 3H+p to 3He+n and 3H+p to 3H+p at a triton momentum of 2.5 GeV/c (equivalent to a proton kinetic energy Tp=318 MeV) have been measured. The ITEP 80 cm hydrogen bubble chamber was exposed to a 2.5 GeV/c separated triton beam. 2350 events of the reaction 3H(p,n)3He and 2574 events of the reaction 3H(p,p)3H were selected and analysed. Calculations performed in the framework of the multiple scattering theory taking the spin-isospin structure of the NN amplitude into account fit the data very well and show the high sensitivity of the charge-exchange cross section to the double spin-flip NN amplitudes.
