Correlations and fluctuations from lattice QCD
  We present the new results of the Wuppertal-Budapest lattice QCD collaboration on flavor diagonal and non-diagonal quark number susceptibilities with 2+1 staggered quark flavors, in a temperature regime between 120 and 400 MeV. A Symanzik improved gauge and a stout-link improved staggered fermion action is utilized; the light and strange quark masses are set to their physical values. Lattices with $N_t=6, 8, 10, 12$ are used. We perform a continuum extrapolation of those observables for which the scaling regime is reached, and discretization errors are under control.
