On the Possibility of Event Shape Selection in Relativistic Heavy Ion Collisions

Understand

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 behaviour 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.
