| dc.description | We report on the first genuinely three-body ${\bar K}NN - πΣN$ coupled-channel Faddeev calculation in search for quasi-bound states in the $K^- p p$ system. The main absorptivity in the $K^- p$ subsystem is accounted for by fitting to $K^- p$ data near threshold. Our calculation yields one such quasi-bound state, with $I=1/2$, $J^π=0^-$, bound in the range $B \sim 55-70$ MeV, with a width of $Γ\sim 95-110$ MeV. These results differ substantially from previous estimates, and are at odds with the $K^- p p \to Λp$ signal observed by the FINUDA collaboration. | |
