Abstract

The NA60 experiment at the CERN SPS has studied meson production meson production in In-In collisions at 158 A GeV via both the K⁺K^- and the μ⁺μ^- decay channels. The yields and inverse slope parameters of the mT mT spectra observed in the two channels are compatible within errors, different from the large discrepancies seen in Pb-Pb collisions between the hadronic (NA49) and dimuon (NA50) decay channels. Possible physics implications are discussed.
