(3+1)D event-by-event pre-equilibrium dynamics in heavy-ion collisions
Xiaojian Du, Sören Schlichting, Jie Zhu
So far a major source of uncertainty in the study of heavy-ion collisions arises from the early time dynamics which includes initial state and pre-equilibrium dynamics. The state-o…

We investigate saturation effects in exclusive vector meson production in deep inelastic scattering (DIS), where we model fluctuations within the target protons as localized color-…

Victor E. Ambrus, Sören Schlichting, Clemens Werthmann
Exploiting the first measurements of the same ion species in OO collisons at RHIC and LHC, we propose an observable to distinguish whether collective behavior builds up through a h…
Collective dynamics in heavy and light-ion collisions -- I) Kinetic Theory vs. Hydrodynamics
Victor E. Ambrus, Sören Schlichting, Clemens Werthmann
High-energy nuclear collisions exhibit collective flow, which emerges as a dynamical response of the Quark-Gluon Plasma (QGP) to the initial state geometry of the collision. Collec…
