multichannel parametrization, Antikaon-Nucleon scattering, amplitudes, extraction, resource parameters
We present results of a new multichannel partial-wave analysis for K¯¯¯N scattering in the center-of-mass (c.m.) energy range from 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.
