  The freeze-out curve, which describes a vast amount of precise experimental
data in heavy ion collisions, provides a relation between the colliding energy
and the thermodynamical parameters of the fireball. The variance, skew and
kurtosis of the event distribution of baryon number are studied at several
energies of interest through Pade resummations of our Lattice QCD results. A
smooth behaviour is predicted for three ratios of these quantities at current
RHIC and future LHC energies. Any deviations from these at the RHIC energy scan
would signal the presence of a nearby critical point. Our lattice results on
the critical point do show such a behaviour.
