Measurement of the in-medium K0 inclusive cross section in pi- -induced reactions at 1.15 GeV/c

Abstract : The K0 meson production by pi- mesons of 1.15 GeV/c momentum on various nuclear targets was measured with the FOPI spectrometer at the SIS accelerator of GSI. Inclusive production cross-sections and the momentum distributions of K0 mesons are compared to the elementary production cross-sections and to QMC and HSD model predictions. The results point to modifications of the elementary reactions amplitudes inside nuclei and to the existence of a repulsive KN potential of about 20 MeV at normal nuclear matter density.
