Description
Sixth and higher order fluctuations of the baryon number are linked
to signals of criticality in heavy ion collisions. The grand canonical
result for these can be obtained from lattice simulations. The
extrapolation to the continuum limit is essential for phenomenologically
relevant results. In fact, higher order coefficients of the Taylor
expansion of the QCD free energy appear to be more sensitive to
discretization effects than lower orders. We meet the challenge in a
modest volume using the new 4HEX fermion action and calculate
the sixth order cumulants in a continuum extrapolation.
