1305.4575 (H. Zhang et al.)

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

H. Zhang, J. Tulpan, M. Shrestha, D. M. Manley
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.
