Strong diffusion effect of charm quarks on J/ψ production in Pb–Pb collisions at the LHC

We study the J/ψ production based on coalescence model at sNN=2.76 and 5.02 TeV Pb–Pb collisions. With the colliding energy increasing from 2.76 TeV to 5.02 TeV, the number of charm pairs is enhanced by more than 50%. However, the ratio of J/ψ inclusive nuclear modification factors RAA5.02 TeV/RAA2....
