Fluctuating shapes of the fireballs in heavy-ion collisions

Abstract

We argue that energy and momentum deposition from hard partons into quark-gluon plasma induces an important contribution to the final state hadron anisotropies. We also advocate a novel method of Event Shape Sorting which allow to analyse the azimuthal anisotropies of the fireball dynamics in more detail. A use of the method in femtoscopy is demonstrated.Comment: contribution to Proceedings of the XXIV Baldin seminar on high energy physics problems (Relativistic Nuclear Physics and Quantum Chromodynamics), Sept. 17-22, 2018, Dubna, Russia, 6 page
