Core-Corona Separation in Ultra-Relativistic Heavy Ion Collisions
read the original abstract
Simple geometrical considerations show that the collision zone in high energy nuclear collisions may be divided into a central part (``core''), with high energy densities, and a peripheral part (``corona''), with smaller energy densities, more like in pp or pA collisions. We present calculations which allow to separate these two contributions, and which show that the corona contribution is quite small (but not negligible) for central collisions, but gets increasingly important with decreasing centrality. We will discuss consequences concerning results obtained in heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) and the Super Proton Synchrotron (SPS).

Characterizing the initial state and dynamical evolution in XeXe and PbPb collisions using multiparticle cumulants
First measurements of mixed-order multiparticle cumulants of flow harmonics v2, v3, and v4 in XeXe collisions at 5.44 TeV compared to PbPb at 5.36 TeV show sensitivity to nuclear deformation and nonlinear hydrodynamic...

Equilibrated fraction of QCD matter in high-energy oxygen--oxygen collisions
The equilibrated core in O+O collisions overtakes the nonequilibrium corona above midrapidity multiplicity of about 20, yet corona contributions persist in central events, making pure hydrodynamics inadequate.
