We have searched for a deeply bound kaonic state by using the FINUDA spectrometer installed at the ee collider DANE. Almost monochromatic K’s produced through the decay of 1020 mesons are used to observe K absorption reactions stopped on very thin nuclear targets.

Abstract

We have searched for a deeply bound kaonic state by using the FINUDA spectrometer installed at the ee collider DANE. Almost monochromatic K’s produced through the decay of 1020 mesons are used to observe K absorption reactions stopped on very thin nuclear targets. Taking this unique advantage, we have succeeded to detect a kaon-bound state Kpp through its two-body decay into a hyperon and a proton. The binding energy and the decay width are determined from the invariant-mass distribution as 1156 5stat3 4syst MeV and 6714 11stat2 3syst MeV, respectively.
