Highlights of the Reaction $\pi^- p \to \pi^- \pi^+ n$ at 100-{GeV}/$c$ and 175-{GeV}/$c$

We present a summary of the physics results from an experimental study of the reaction π−p→π−π+n at 100 and 175 GeV/c incident-beam momentum. Our data show the continuing dominance of one-pion exchange in these reactions with the characteristic 1Plab2 momentum dependence. We extract the pion Regge trajectory from our data on π−p→ρ0n and study the zero structure of the ππ differential cross section up to sππ=12 GeV2.

Reaction pi+ p ---> rho+ p at 2.67 gev/c - a study of isoscalar exchanges

Results are presented of a study of the reaction π+p→ρ+p at 2.67 GeV/c incident π+ momentum. The contributions due to given spin-parity exchanges are isolated; and, by combining these results with those of a similar π− experiment, the It=0 component of each series is separated. The ω (I=0, JPG=1−−) exchange contribution shows a pronounced dip at −t=0.4 (GeV/c)2. Evidence is presented for the exchange of a state of minimum quantum numbers, H (I=0, JPG=1+−).
