Critical review of [K- ppn] bound states

Magas, V. K., Oset, E., Ramos, A.

Understand

We make a thorough study of the process of three body kaon absorption in nuclei, in connection with a recent FINUDA experiment which claims the existence of a deeply bound kaonic state from the observation of a peak in the Lambda d invariant mass distribution following K- absorption on Li6.

We show that the peak is naturally explained in terms of K- absorption from three nucleons leaving the rest as spectators.
We can also reproduce all the other observables measured in the same experiment and used to support the hypothesis of the deeply bound kaon state.
Our study also reveals interesting aspects of kaon absorption in nuclei, a process that must be understood in order to make progress in the search for K- deeply bound states in nuclei.
