Phys. Rev. Lett. 98, 082301 (2007) [4 pages]Faddeev Calculation of a K-pp Quasibound StateReceived 11 October 2006; published 22 February 2007 We report on the first genuinely three-body K̅ NN-πΣN coupled-channel Faddeev calculation in search for quasibound states in the K-pp 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 quasibound state, with I=1/2, Jπ=0-, bound in the range B∼55–70 MeV, with a width of Γ∼90–110 MeV. These results differ substantially from previous estimates, and are at odds with the K-pp→Λp signal observed by the FINUDA collaboration. © 2007 The American Physical Society URL:
