phi puzzle in heavy-ion collisions at 2 AGeV: how many K-from phi decays?

Abstract

The preliminary experimental data on $\varphi$ production in the reaction Ni(1.93 AGeV) + Ni point to a puzzling high $\varphi$ yield which can not be reproduced with present transport codes. We survey the experimental situation and present prospects for dedicated measurements of the $\varphi$ multiplicities with the $K^{+}{K}^{-}$ and $e^{+}{e}^{-}$ channels at HADES and FOPI.
