Quantum mechanical model for J/psi suppression in the LHC era

We discuss the effects of screening and absorption in a strongly correlated plasma medium on the quantum mechanical evolution of quarkonia states within time-dependent harmonic oscillator model with complex oscillator strength. We compare the results with data for R_AA/R_AA(CNM) from RHIC and SPS experiments and extrapolate to the LHC domain where first data have appeared recently, but still no cold nuclear matter (CNM) effects are analyzed. We discuss the peculiar temperature dependence of real and imaginary parts of the oscillator strength in view of the recently found X(3872) state in the charmonium spectrum and possible regeneration effects in the kinetics of charmonium production in heavy-ion collisions.
