A comparative measurement of and in In-In collisions at the CERN SPS
NA60 Collaboration, R. Arnaldi, K. Banicz +49
The NA60 experiment at the CERN SPS has studied meson production in In-In collisions at 158A GeV via both the and the decay channels. The yields and inverse s…
Determination of chi_c and chi_b polarizations from dilepton angular distributions in radiative decays
Pietro Faccioli, Carlos Lourenco, Joao Seixas +1
The angular distributions of the decay products in the successive decays chi_c (chi_b) to J/psi (Upsilon) gamma and J/psi (Upsilon) to l+l- are calculated as a function of the angu…
Model-independent constraints on the shape parameters of dilepton angular distributions
Pietro Faccioli, Carlos Lourenco, Joao Seixas +1
The coefficients determining the dilepton decay angular distribution of vector particles obey certain positivity constraints and a rotation-invariant identity. These relations are…
Rotation-invariant observables in parity-violating decays of vector particles to fermion pairs
Pietro Faccioli, Carlos Lourenco, Joao Seixas +1
The di-fermion angular distribution observed in decays of inclusively produced vector particles is characterized by two frame-independent observables, reflecting the average spin-a…
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…
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…
