Nuclear surface effects in heavy-ion collisions at RHIC and SPS
Klaus Werner1

One may divide the collision zone in nuclear collisions into a central part ('core') with expected high energy densities, and a peripheral part ('corona') with smaller energy densities more like in pp or pA collisions. We discuss the consequences of the core–corona separation within the EPOS approach. The complicated centrality dependence of hadron yields observed at RHIC and SPS becomes almost trivial after subtracting the corona background.
