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