| Abstract | |
The correlation between the mean transverse momentum of outgoing particles, < p(t)>, and the magnitude of anisotropic flow, v(n), has recently been measured in Pb + Pb collisions at the CERN Large Hadron Collider, as a function of the collision centrality. We confirm the previous observation that event-by-event hydrodynamics predicts a correlation between v(n) and < p(t)> that is similar to that measured in data. We show that the magnitude of this correlation can be directly predicted from the initial condition of the hydrodynamic calculation, for n = 2, 3, if one replaces v(n) by the corresponding initial-state anisotropy, epsilon(n), and < p(t)> by the total energy per unit rapidity of the fluid at the beginning of the hydrodynamic expansion.
