Topological susceptibility and ${\eta }^{\prime }$ meson mass from $N_f=2$ lattice QCD at the physical point

Petros Dimopoulos, Christopher Helmes, Christian Jost +8

In this paper we explore the computation of topological susceptibility and ${\eta }^{\prime }$ meson mass in $N_f=2$ flavor QCD using lattice techniques with physical value of the pion mass as we…
