$\pi \pi$ phase-shift analysis from an experiment $\pi^{-}p \rightarrow \pi^{-} \pi^{+} n$ at 17.2 GeV/c
The pi pi phase-shifts have been determined by a Chew-Low extrapolation in the pi pi mass region from 500 to 1500 MeV using data of a spark chamber experiment on pi /sup -/p to pi /sup -/ pi /sup +/n at 17.2 GeV/c, which yielded 318000 events. The authors find an I=0 s- wave phase shift which increa...

| description | The pi pi phase-shifts have been determined by a Chew-Low extrapolation in the pi pi mass region from 500 to 1500 MeV using data of a spark chamber experiment on pi /sup -/p to pi /sup -/ pi /sup +/n at 17.2 GeV/c, which yielded 318000 events. The authors find an I=0 s- wave phase shift which increases slowly, passing through 90 degrees near 900 MeV, and then rises very rapidly. The old 'up' solution is eliminated on the basis of fits in the mass region from 900-1000 MeV. (13 refs). |
