First measurement of the ϱ spectral function in nuclear collisions
Abstract The NA60 experiment at the CERN SPS has studied low-mass muon pairs in 158 A GeV In–In collisions. A strong excess of pairs is observed above the yield expected from neutral meson decays. The unprecedented sample size close to 400000 events and the good mass resolution of about 2% made it p...

| 520 | |a Abstract The NA60 experiment at the CERN SPS has studied low-mass muon pairs in 158 A GeV In–In collisions. A strong excess of pairs is observed above the yield expected from neutral meson decays. The unprecedented sample size close to 400000 events and the good mass resolution of about 2% made it possible to isolate the excess by subtraction of the decay sources. The shape of the resulting mass spectrum shows some non-trivial centrality dependence, but is largely consistent with a dominant contribution from $ π^{+} $$ π^{-} $→ϱ→$ μ^{+} $$ μ^{-} $ annihilation. The associated ϱ spectral function exhibits considerable broadening, but essentially no shift in mass. The $ p_{T} $-differential mass spectra show the excess to be much stronger at low $ p_{T} $ than at high $ p_{T} $. The results are compared to theoretical model predictions; they tend to rule out models linking hadron masses directly to the chiral condensate. | ||

Abstract The NA60 experiment at the CERN SPS has studied low-mass muon pairs in 158 A GeV In–In collisions. A strong excess of pairs is observed above the yield expected from neutral meson decays. The unprecedented sample size close to 400000 events and the good mass resolution of about 2% made it possible to isolate the excess by subtraction of the decay sources. The shape of the resulting mass spectrum shows some non-trivial centrality dependence, but is largely consistent with a dominant contribution from $ π^{+} $$ π^{-} $→ϱ→$ μ^{+} $$ μ^{-} $ annihilation. The associated ϱ spectral function exhibits considerable broadening, but essentially no shift in mass. The $ p_{T} $-differential mass spectra show the excess to be much stronger at low $ p_{T} $ than at high $ p_{T} $. The results are compared to theoretical model predictions; they tend to rule out models linking hadron masses directly to the chiral condensate. © Springer-Verlag Berlin Heidelberg 2006 |
