Description

Fluctuations of conserved charges in a grand canonical ensemble
can be computed on the lattice and, thus, provide theoretical
input for freeze-out phenomenology in heavy ion collisions.
Electric charge fluctuations and the corresponding higher order
correlators are extremely difficult, suffering form the most severe
lattice artefacts. We present new simulation data with a novel
discretization where these effects are strongly suppressed and provide
continuum extrapolated results in the temperature region of the chemical
freeze-out.
