Abstract / Bemerkung
A possible effective restoration of the anomalous UA(1)U_A(1)UA​(1) symmetry would have a non-trivial effect on the global phase diagram of QCD. In this work we investigate the effective restoration of the UA(1)U_A(1)UA​(1) through the calculation of scalar and pseudo-scalar screening masses and corresponding susceptibilities, for physical and lower than physical pion masses. Calculations have been performed in (2+1)-flavor HISQ discretization scheme with a physical value of the strange quark mass. Preliminary calculations of the continuum extrapolated scalar and pseudo-scalar masses are presented, based on lattices with three different temporal extent. Non-trivial structure of the difference between scalar and pseudo-scalar susceptibilites are discussed for Nτ=8N_\tau=8Nτ​=8 lattices.
