Query: Behavior and finite-size effects of the sixth order cumulant in the
  three-dimensional Ising universality class   The high-order cumulants of conserved charges are suggested to be sensitive
observables to search for the critical point of Quantum Chromodynamics (QCD).
This has been calculated to the sixth order in experiments. Corresponding
theoretical studies on the sixth order cumulant are necessary. Based on the
universality of the critical behavior, we study the temperature dependence of
the sixth order cumulant of the order parameter using the parametric
representation of the three-dimensional Ising model, which is expected to be in
the same universality class as QCD. The density plot of the sign of the sixth
order cumulant is shown on the temperature and external magnetic field plane.
We found that at non-zero external magnetic field, when the critical point is
approached from the crossover side, the sixth order cumulant has a negative
valley. The width of the negative valley narrows with decreasing external
field. Qualitatively, the trend is similar to the result of Monte Carlo
simulation on a finite-size system. Quantitatively, the temperature of the sign
change is different. Through Monte Carlo simulation of the Ising model, we
calculated the sixth order cumulant of different sizes of systems. We discuss
the finite-size effects on the temperature at which the cumulant changes sign.
