Formation of π pairs in nuclear captures of K- mesons
Abstract
The capture of K- mesons on nucleons bound in nuclei offer a chance to study the π pairs below the kinematic threshold of the KN systems. Various hyperon-pion charged combination are presently under investigation by AMADEUS. These data allow to test both isospin 0 and 1 amplitudes giving the possibility to detect the structure of resonant (1405) state. Contrasted against similar electro-production data, it is possible to detect changes of (1405) in nuclear media. Expected spectra and their uncertainties are calculated.
