Search for the critical point of strongly interacting matter in NA49

Abstract

Theoretical calculations locate the QCD critical point at energies accessible at the CERN SPS. Several observables were suggested to look for it. Here, we present the system size dependence and the energy dependence of event-by-event mean transverse momentum and multiplicity fluctuations, as well as the energy dependence of anti-baryon to baryon ratios.
