Description
We measure the connected and disconnected mesonic correlators and
screening masses in the high-temperature phase of $N_f=2$ QCD. Gauge
ensembles are generated with Mobius domain-wall fermions, while the
observables are calculated with a reweighting to achieve more precise
chiral symmetry. We confirm the restoration of axial $U(1)$ symmetry for
small quark masses. At a larger quark mass, the $U(1)_A$ is broken and
long-distance correlations are observed in the isospin singlet channels.
