Abstract
New data on Ï-meson production in pp collisions have been obtained at the ANKE facility of COSY-Jülich. These data will provide the energy dependence of the total cross section down to an excess energy of 19 MeV above threshold. In combination with the existing SPES-III and COSY-TOF results on Ï-meson production the Ï/Ï production ratio at this low excess energy will be extracted. As an exciting new aspect an enhancement in the invariant Ïp mass spectrum is observed at a mass around 1.965Â GeV/c2.
