Multichannel parametrization of $\bar{K}N$ scattering amplitudes and extraction of resonance parameters

Abstract

We present results of a new multichannel partial-wave analysis for $\bar{K}N$ scattering in the c.m.\ energy range 1480 to 2100 MeV. Resonance parameters were extracted by fitting partial-wave amplitudes from all considered channels using a multichannel parametrization that is consistent with $S$-matrix unitarity. The resonance parameters are generally in good agreement with predictions of the Koniuk-Isgur quark model.
