Pion-nucleon charge exchange measurement ; AGS
Sažetak
An update of recent measurements of pion-nucleon charge-exchange scattering is presented. these consist primarily of cross sections at 150-660 MeV/c obtained with the Crystal Ball detector. They are the first results of a rich and diverse new experimental program in baryon spectroscopy at the Alternating Gradient Synchrotron at Brookhaven National Laboratory. The physics motives for making more accurate measurements of Pi^-p->Pi^0n in this region are to determine better the isospin-odd s-wave scattering length, to extrapolate scattering amplitudes to the non-physical region (e.g., for determinations of the PiN Sigma term), to evaluate the PiNN coupling constant and the mass splitting of the Delta resonance, to improve the determination of the mass, width and decay of the P_11(1440) resonance and to investigate isospin invariance and charge splitting of the P_33 scattering amplitude.
