Analyzing powers for the Pi- P(Polarized) -> Pio N Reaction across the Delta (1232) Resonance
In the LAMPF experiment Pi- P(Polarized) -> Pio N reaction have been obtained over a broad angular range at incident kinetic energies of 98.1, 138.8, 165.9 and 214.4 MeV. High quality data for this change-exchange reaction are sparse. Analyzing-power measurements for the PiN system are particularly sensitive to the interference between partial waves, and can provide crucial information for partial-wave decompositions of the PiN amplitudes. These measurements will help to quantify topics such as the violation of isospin invariance in the PiN system across the Delta(1232) resonance and the negative-energy extrapolation of the PiN amplitudes for extraction of the PiN sigma term.
