$\psi^{\prime}$ production in Pb-Pb collisions at 158 GeV/nucleon

$\psi{prime}$ production is studied in Pb-Pb collisions at 158 GeV/c per nucleon incident momentum. Absolute cross-sections are measured and production rates are investigated as a function of the centrality of the collision. The results are compared with those obtained for lighter colliding systems...

Descripción
Sumario:$\psi{prime}$ production is studied in Pb-Pb collisions at 158 GeV/c per nucleon incident momentum. Absolute cross-sections are measured and production rates are investigated as a function of the centrality of the collision. The results are compared with those obtained for lighter colliding systems and also for the $J/\psi$ meson produced under identical conditions.
