Query: On the sign of kurtosis near the QCD critical point   We point out that the quartic cumulant (and kurtosis) of the order parameter
fluctuations is universally negative when the critical point is approached on
the crossover side of the phase separation line. As a consequence, the kurtosis
of a fluctuating observable, such as, e.g., proton multiplicity, may become
smaller than the value given by independent Poisson statistics. We discuss
implications for the Beam Energy Scan program at RHIC.
