The estimates of the critical point from lattice studies are shown in (a), from [137]. The magenta solid circle, box, and star denote the data, respectively, for 2 flavours of staggered quarks [135–137], and the open circles denote data for flavours obtained with reweighting techniques [87, 133]. In (b), the ratio of the third and the second order baryon number susceptibility is plotted as a function of relevant for the RHIC and LHC experiments and compared with the HRG model data, from [108].
