Search for the critical point of strongly interacting matter in NA49

Understand

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.
