Description
We present preliminary lattice results for the topological susceptibility in high-temperature $N_f=2+1$ QCD obtained discretizing this observable via spectral projectors on eigenmodes of the staggered operator, and we compare them with those obtained with the standard gluonic definition.
The adoption of the spectral discretization is motivated by the large lattice artifacts affecting the continuum scaling of the gluonic susceptibility at high temperatures, related to the choice of non-chiral fermions in the action.
