Beschreibung
Highly-energetic heavy-ion collisions are known to produce a viscous relativistic fluid with a very short lifetime that we call Quark-Gluon Plasma (QGP). For such a system to form we need an extraordinarily rapid thermalization that has been explained within the kinetic theory framework for longitudinally boost-invariant expanding systems. These studies assume that the system has an infinite transverse size, as in Bjorken flow. This kind of setup always thermalizes, but this is not always true if the system size is small enough. In this talk, we relax the assumption of infinite transverse size and perform a study of system size dependent hydrodynamization in QCD kinetic theory to address the question of which is the smallest possible droplet of QGP that can be produced.
