Constraints on the size of the quark gluon plasma

Abstract

We use simple entropy arguments to estimate the possible size of the QGP at the AGS and the SPS. We find that the possibility to form a large volume of QGP at the AGS or the SPS is very small. The size of the QGP at RHIC and the LHC is also predicted.

new references of finite size effects on the observables are added
