Possibility of event shape selection in relativistic heavy ion collisions


Journal Article

We investigate the possibility of selecting heavy ion collision events with certain features in the initial state (event engineering). Anisotropic flow measurements in heavy ion reactions have confirmed the almost ideal fluid dynamical behavior of the hot and dense quark-gluon plasma state. As a consequence, it is intriguing to pursue the idea of selecting collisions with a certain special initial geometry, e.g., a large ellipsoidal or triangular deformation, by classifying events by the value of their final observed flow coefficients. This procedure could be especially interesting for azimuthally dependent jet energy loss studies. We investigate the correlation between initial state features and final state momentum space anisotropies within an event-by-event hybrid approach. We find that the finite particle number and hadronic rescattering of the final state leads to large event-by-event fluctuations in the observables that could be used to characterize the features of the initial state. This makes event engineering by final state selection difficult. © 2013 American Physical Society.
