Abstract
Resent results concerning the production of K_s16, K-, phi, K0 S and lambda particles in the reaction system Ar_s16KCl at 1.76 AGeV measured by the HADES Collaboration are presented. Transverse momentum distributions have been measured in a large fraction of the phase space. For the first time, at SIS energies, K_s16, K- and phi mesons have been measured independently and the slope parameter for phi mesons could be extracted. A large statistics has been collected for the produced K0S and lambda in the phase space region around mid-rapity. The high quality of these data render them very suitable for comparisons with theoretical models.
