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. 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.
