We investigate J/psi transverse momentum distribution in a transport approach. While the nuclear modification factor R_{AA}(N_p) at RHIC is almost the same as at SPS, the averaged transverse momentum square <p_t^2> and R_{AA}(p_t) are very…

Large p_T transverse momentum distributions exhibit apparently a power-like behavior. We argue that, under closer inspection, this behavior is in fact decorated with some log-periodic oscillations. Assuming that this is genuine effect and…
