Query: Establishing mass spectrum of $S=-1$ hyperon resonances via a dynamical
  coupled-channels analysis of $K^-p$ reactions   We report our recent effort for the extraction of resonance parameters
(complex pole mass and residues etc.) associated with Lambda* and Sigma*
hyperons. This was accomplished via a comprehensive partial-wave analysis of
the data for K^- p --> barK N, pi Sigma, pi Lambda, eta Lambda, K Xi reactions
from the thresholds up to W=2.1 GeV within a dynamical coupled-channels
approach. The results suggest a possible existence of new narrow J^P=3/2^+
\Lambda resonance with pole mass 1671^{+2}_{-8} -i(5^{+11}_{-2}) MeV, located
close to the eta Lambda threshold. This resonance is found to be responsible
for reproducing the data for K^-p --> eta Lambda differential cross sections
near the threshold, and thus the data seem favor its existence. The extracted
poles for J^P=1/2^- Lambda resonances below the barK N threshold, including
Lambda(1405), are also presented.
