Total branching ratio of the K-two-nucleon absorption in 12C

This work is a critical re-analysis of the results obtained by the AMADEUS collaboration, concerning the measurement of the K− multi-nucleon absorption reactions, on a 12C target, in the Λp final state. We show that a good estimate of the K− two-nucleon absorption total branching ratio can be extrac...
