Query: Coupled channel Faddeev calculations of a (Kbar-N-pi) quasibound state   The (Kbar-N-pi) system is studied using separable interactions fitted to data
available on the s-wave (Kbar-N)--(pi-Y) subsystem and the p-wave
(pi-N),(pi-Y),(pi-pi) and (pi-Kbar) subsystems. Three-body
(Kbar-N-pi)--(pi-Y-pi) coupled channel Faddeev equations with relativistic
kinematics are solved in search for quasibound poles in the complex plane,
leading to a I(JP)=1(3/2-) (Kbar-N-pi) quasibound state at M ~ (1570 +/- 10)
MeV and width greater than 60 MeV near the (Kbar-N-pi) threshold. A D13
Sigma(1570) resonance of molecular structure is thus predicted.
