Further Evidence on New Resonances in theK¯NSystem

Abstract

Utilizing the $K^{-}p$ charge-exchange results from the previous Letter, we report an energy-dependent partial-wave analysis of all available $\overline{K}N$ data from 365 to 1320 MeV/c. The effects observed at $\Lambda \eta$ and ${\Sigma }^0\eta$ thresholds are well described by cusps. New values of masses and widths are found for the $P_{01}$ and $P_{11}$ resonances. No new narrow resonances are required.
