摘要：
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(-)pp ->Lambda p followed by final-state interactions of the produced particles with the daughter nucleus.
