Low Mass Dimuon Production in Indium-Indium Collisions at the CERN SPS
NA60 Collaboration, M. Floris, R. Arnaldi +48
NA60 is a fixed-target experiment at the CERN SPS which measured dimuon production in nucleus-nucleus and proton-nucleus collisions. In this paper we report on a precision measurem…
J/psi production in Indium-Indium collisions at 158 GeV/nucleon
NA60 Collaboration, R. Arnaldi
The NA60 experiment studies muon pair production at the CERN SPS. In this letter we report on a precision measurement of J/psi in In-In collisions. We have studied the J/psi centra…
Evidence for the production of thermal muon pairs with masses above 1 GeV/c^2 in 158A GeV Indium-Indium Collisions
NA60 Collaboration, R. Arnaldi, K. Banicz +50
The yield of muon pairs in the invariant mass region 1<M<2.5 GeV/c^2 produced in heavy-ion collisions significantly exceeds the sum of the two expected contributions, Drell-Yan dim…
Precision study of the and electromagnetic transition form-factors and of the line shape in NA60
NA60 Collaboration
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. The low-mass dimuon spectrum is well descr…
First Measurement of the rho Spectral Function in High-Energy Nuclear Collisions
NA60 Collaboration, R. Arnaldi
We report on a precision measurement of low-mass muon pairs in 158 AGeV indium-indium collisions at the CERN SPS. A significant excess of pairs is observed above the yield expected…
Evidence for radial flow of thermal dileptons in high-energy nuclear collisions
NA60 Collaboration, R. Arnaldi
The NA60 experiment at the CERN SPS has studied low-mass dimuon production in 158 AGeV In-In collisions. An excess of pairs above the known meson decays has been reported before. W…
