Analysis of $\pi^{-}p \rightarrow \pi^{-} \pi^{+}n$ data at 17.2 GeV/c

The authors propose an amplitude analysis for pi /sup -/p to pi /sup - / pi /sup +/n data which allows for the possibility of A/sub 2/ exchange as well as absorbed pion exchange in a model independent way. This leads to an improved extrapolation method for extracting pi pi phase shifts. Using the re...

description The authors propose an amplitude analysis for pi /sup -/p to pi /sup - / pi /sup +/n data which allows for the possibility of A/sub 2/ exchange as well as absorbed pion exchange in a model independent way. This leads to an improved extrapolation method for extracting pi pi phase shifts. Using the recent CERN-Munich data at 17.2 GeV/c the authors isolate the pi and A/sub 2/ exchange contributions and determine the form of the absorptive corrections. No evidence for an exchange contribution with the quantum numbers of the A/sub 1/ is found. (14 refs).
