“…In the range B K − ∼ 100−200 MeV the width is dominated by the two-nucleon absorption modes. Here, the calculated widths for 12 C, 16 O and 40 Ca assume values Γ K − = 45 ± 5 MeV, about a factor of two higher than what the static nuclear-matter calculation gives. This is due to the dynamical nature of the calculation whereby the nuclear density is enhanced.…”

“…Another very recent candidate for an extremely deep and narrow K − pp state, with B K − pp ≈ 160 MeV and Γ ≈ 30 MeV has been observed in decay Λp pairs, usingp annihilation data on 4 He at LEAR, CERN [15]. Finally, preliminary evidence for a surprisingly narrowKNNN quasi-bound state (B ≈ 60 MeV, Γ ≈ 35 MeV) has been reported by the FINUDA Collaboration on 6 Li by observing back-to-back Λd pairs [16].…”

“…The acceptance function for protons was calculated with simulated tracks and taking into account only geometrical effects. In the present analysis we required for the measurement of the proton momenta even tracks reconstructed by means of three points only (short tracks) provided by the inner detectors (two arrays of Si microstrip detectors and the two layers of Drift Chambers) [18]. The threshold on the detection energy of protons was then lowered to 15 MeV.…”

The results of a measurement of the proton spectra following the Non-Mesonic Weak Decay of 5 Λ He, 7 Λ Li and 12 Λ C are presented and discussed. The experiment was performed at the (e + e − ) collider DAΦNE at Laboratori Nazionale di Frascati of INFN.It is the first measurement for 7 Λ Li, and for all the spectra the lower limit on the energy of the protons is 15 MeV, never reached before. All the spectra show a similar shape, namely a peak at around 80 MeV as expected for the free Λp → np weak reaction, with a low energy rise that should be due to Final State Interactions and/or two-nucleon induced weak processes. The decay spectrum of 5 Λ He is somehow similar to the ones reported by previous measurements and theoretical calculations, but the same doesn't happen for the 12 Λ C one.

“…The peaks seen by FINUDA and originally interpreted in terms of deeply bound K − pp [19] and K − ppn [20] clusters, are now put under the question, because in Refs. [21,22,23,24] these peaks found explanations based on conventional reactions that unavoidably occur in the process of kaon absorption.…”
