New Charge-Exchange Polarization Data andπN-Amplitude Analyses at 3.6 and 6.0 GeV/c

Abstract

Using the results of recent $\pi N$ charge-exchange polarization measurements at Argonne National Laboratory we have determined the amplitudes for $\pi N$ scattering 3.6 and 6.0 GeV/c. Two different methods, individual $t$-by-$t$ analysis and $t$-dependent analysis, have been adopted, and uncertainties of these amplitudes are discussed.
