We report on a precision measurement of low-mass muon pairs in 158 AGeV indium-indium collisions at the CERN SPS. A significant excess is observed above yield expected from neutral meson decays. The unprecedented sample size 360 000 dimuons and good mass resolution about 2% allow us to isolate by subtraction decay sources. shape resulting spectrum consistent with dominant contribution...
The NA60 experiment at the CERN SPS has studied low-mass muon pairs in 158A GeV In-In collisions. mass and pT spectra associated with peripheral collisions can quantitatively be described by known neutral meson decays. high data quality allowed to remeasure electromagnetic transition form factors of Dalitz decays η-> μ^+μ^-γand ω-> μ^+μ^-π^0. Using usual pole approximation F = (1-M_{μμ}^{2}/Λ^{2})^{-1} for factors, we find Λ^{-2} (in GeV^{-2}) 1.95+-0.17(stat.)+-0.05(syst.) ηand...
The NA60 experiment studies muon pair production at the CERN Super Proton Synchrotron. In this Letter we report on a precision measurement of J/ψ in In-In collisions. We have studied centrality distribution, and compared it with one expected if absorption cold nuclear matter were only active suppression mechanism. For collisions involving more than ∼80 participant nucleons, find that an extra is present. This result qualitative agreement previous Pb-Pb measurements by NA50 experiment, but no...
The NA60 experiment at the CERN SPS has studied low-mass dimuon production in 158A GeV In-In collisions. An excess of pairs above known meson decays been reported before. We now present precision results on associated transverse momentum spectra. slope parameter Teff extracted from spectra rises with mass up to ρ, followed by a sudden decline above. While initial rise is consistent expectations for radial flow hadronic decay source, signals transition an emission source much smaller flow....
The NA60 experiment at the CERN SPS has measured muon pairs with unprecedented precision in 158A GeV In-In collisions. A strong excess of above known sources is observed whole mass region 0.2 rho -> mu+mu- annihilation. associated spectral function shows a broadening, but essentially no shift mass. For M>1 GeV, found to be prompt, not due enhanced charm production, pronounced differences Drell-Yan pairs. slope parameter Teff transverse momentum spectra rises up rho, followed by sudden...
The NA60 experiment studied low-mass muon pair production in proton–nucleus (p–A) collisions using a 400 GeV proton beam at the CERN SPS. dimuon spectrum is well described by superposition of two-body and Dalitz decays light neutral mesons η, ρ, ω, η′ ϕ, no evidence in-medium effects found. A new high-precision measurement electromagnetic transition form factors η ω was performed, profiting from 10 times larger data sample than peripheral In–In previously collected NA60. Using...
The observation of an anomalous J/ψ suppression in Pb–Pb collisions by the NA50 Collaboration can be considered as most striking indication for deconfinement quarks and gluons at SPS energies. In this Letter, we determine pattern a function forward hadronic energy EZDC measured Zero Degree Calorimeter (ZDC). direct connection between geometry collision allows us to calculate, within Glauber approach, precise relation number participant nucleons Npart EZDC. Then, check if experimental data...
The NA60 experiment at the CERN SPS has studied dimuon production in 158A GeV In-In collisions. strong excess of pairs above known sources found complete mass region 0.2<M<2.6 previously been interpreted as thermal radiation. We now present first results on associated angular distributions. Using Collins-Soper reference frame, structure function parameters \lambda, \mu and \nu are measured to be zero, projected distributions polar azimuth angles uniform. absence any polarization is...
The NA60 experiment has measured muon pair production in In-In collisions at 158 AGeV the CERN SPS. This paper presents a high statistics measurement of $ϕ\toμμ$ meson production. Differential spectra, yields, mass and width are as function centrality compared to previous measurements other colliding systems same energy. rapidity distribution is found be constant centrality, compatible with results. decay polar angle several reference frames. No evidence polarization transverse momentum...
