Triangularity and dipole asymmetry in relativistic heavy ion collisions
Triangularity and dipole asymmetry in relativistic heavy ion collisions
We introduce a cumulant expansion to parameterize possible initial conditions in relativistic heavy ion collisions. We show that the cumulant expansion converges and that it can systematically reproduce the results of Glauber type initial conditions. At third order in the gradient expansion, the cumulants characterize the triangularity $<r^3 \cos3(\phi - …
