A comparative measurement of ϕ→K+K− and ϕ→μ+μ− in In-In collisions at the CERN SPS

The NA60 experiment at the CERN SPS has studied ϕ 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 spectra observed in the two channels are compatible within errors, different from the large discrepanci...
