Partial-wave analysis of $\bar{K}N$ scattering reactions

Abstract

We investigate the two-body reactions $\bar{K}N\to \bar{K}N$, $\bar{K}N\to \pi \Lambda$, and $\bar{K}N\to \pi \Sigma$ via single-energy partial-wave analyses in the c.m.\ energy range 1480 to 2100 MeV. The partial-wave amplitudes for these reactions thus extracted were constrained by a multichannel energy-dependent model satisfying unitarity of the partial-wave $S$-matrix. We obtain excellent predictions of differential cross sections, polarizations, polarized cross sections, and cross sections for these reactions from a global energy-dependent solution.
