Abstract

The authors study the fluctuations of baryon number at finite temperature and density near the QCD phase transition from quark-gluon plasma to hadronic matter. Performing the calculations up to tenth order, they find a non-monotonic dependence of baryon number fluctuations on collision energy, which can arise in the non-critical crossover region of the phase diagram. The results compare well with recent experimental measurements from the STAR collaboration.
