phi decay: A relevant source for K- production at energies available at the GSI Schwerionen-Synchrotron (SIS)?

Abstract : We present phase space distributions and multiplicities of K+, K-, and phi mesons produced in Ar+KCl reactions at a kinetic beam energy of 1.756 GeV/nucleon and measured with the HADES spectrometer. The inverse slope parameters and yields of kaons supplement the systematics of previous measurements. The percentage of K- mesons coming from phi decay is found to be 18±7%.
