Chiral dynamics of Kbar- nucleus interaction:
critical review of deeply bound K¯ states
Abstract
A brief discussion of the Kbar N interaction will be given, as well as the many body techniques used to evaluate the K- interaction with a nuclear medium.
Comparison with present data on K¯ atoms will be done and predictions for deeply bound states will be shown, with states bound around 50 MeV binding but widths twice as big.
A critical revision of the peaks found at KEK and FINUDA will be made, showing that these peaks come naturally from some reaction mechanism in the experiments, without the need to invoke the creation of deep and narrow K¯ bound states.
