Results on charged pion and kaon production in central Pb+Pb collisions at 20A and 30A GeV are presented and compared to data at lower and higher energies. Around 30A GeV a rapid change of the energy dependence for the yields of pions and kaons as well as for the shape of the transverse mass spectra is observed. The change is compatible with the prediction that the threshold for production of a state of deconfined matter at the early stage of the collisions is located at low CERN Super Proton Synchroton energies.

• Properties of hot and dense matter from relativistic heavy ion collisions (2015, background): “The non-monotonic dependence on energy of theK/π yield ratio was originally proposed as a signature [138], and the measurement by the NA49 collaboration taken as evidence [139] for the onset of deconfinement.”
