Production of J/Ψ mesons in p–Pb collisions at the Large Hadron Collider

Sammanfattning: Data from p–Pb collisions reconstructed with the ALICE experiment at √s = 5.02 TeV is analyzed to study J/Ψ production (a possible Quark Gluon Plasma signal) in different pT ranges. Results obtained by studying the invariant mass distribution via the dielectron decay channel show a significant J/Ψ yield from approximately pT > 2 GeV/c with statistics up to about 10 GeV/c. The signal is observed via Unlike-Sign pairs, and the combinatorial background is estimated via Like-Sign pairs.
