A critical view on the deeply bound K^- pp system
We briefly review the situation around the claimed deeply bound K^- states in
different recent experiments and concentrate particularly on the state K^- pp
advocated by the FINUDA collaboration in nuclear K^- absorption. We perform a
theoretical simulation of the process and show that the peak in the Lambda p
spectrum that was interpreted as a deep K^- pp bound state corresponds mostly
to the process K^- p p --> Lambda p followed by final state interactions of the
produced particles with the daughter nucleus.Comment: 11 pages, 14 figure
