J an 2 00 6 A critical view on the deeply bound K − pp system March 18 , 2008
We briefly review the situation around the claimed deeply bound K states in different recent experiments and concentrate particularly on the state Kpp seen by the FINUDA collaboration in nuclear K absorption. We perform a theoretical simulation of the process and show that the peak in the Λp spectrum that was interpreted as a deep Kpp bound state corresponds mostly to the process Kpp → Λp follo...
متن کاملNew way to produce dense double-antikaonic dibaryon system, 𝐾̄𝐾̄NN, through Λ(1405)-doorway sticking in p + p collisions
A recent successful observation of a dense and deeply bound K nuclear system, K-pp, in the p+p→K++K-pp reaction in a DISTO experiment indicates that the double-K dibaryon, K-K-pp, which was predicted to be a dense nuclear system, can also be formed in p+p collisions. We find theoretically that the K--K- repulsion plays no significant role in reducing the density and binding energy of K-K-pp and...
متن کاملA theoretical view on bound antikaon-nuclear states
We present an overview of the latest theoretical studies on the antikaon properties in the nuclear medium, in connection with the recent experimental claims of very deeply bound antikaon-nuclear states. We argue that proper many-body formulations using modern realistic antikaon-nucleon interactions are not able to generate such systems. Instead, a simple two-nucleon antikaon absorption mechanis...
متن کاملبررسی سیستم جفت شده K ̅K ̅N-πK ̅Σ با استفاده از روش فدیف
Base on the non-relativistic Faddeev AGS method, three-body calculations of the coupled and quasi-bound KKN-πKΣ system are performed in the momentum space. Different phenomenological models of KN-πΣ potentials with one and two-pole structures of KN-πΣ resonance are used to study the dependence of double-kaonic system binding energy on the coupled KN-πΣ interaction. Also, the effect of the KK r...
متن کاملSe p 20 05 A critical analysis on deeply bound kaonic states in nuclei
We make a critical analysis on the theoretical calculations that lead to predictions of deeply bound kaonic states in nuclei. The model set-up, after dropping several important processes and channels, leads unavoidably to an unrealistic deep potential with a very small imaginary part. We review also the experimental results taken as reference for the claim of deeply bound kaons. We suggest that...
