Continuum extrapolated high order baryon fluctuations
Abstract
Fluctuations play a key role in the study of QCD phases. Lattice QCD is a valuable tool to calculate them, but going to high orders is challenging. Up to the fourth order, continuum results are available since 2015. We present the first continuum results for sixth order baryon fluctuations for temperatures between T=130 - 200 MeV, and eighth order at T=145 MeV in a fixed volume. We show that for T ≤ 145 MeV, relevant for criticality search, finite volume effects are under control. Our results are in sharp contrast with well known results in the literature obtained at finite lattice spacing.
