$\eta$, ${\eta }^{\prime }$ mesons from lattice QCD in fully physical conditions

Konstantin Ottnad, Simone Bacchio, Jacob Finkenrath +5

We determine masses and mixing parameters of the $\eta$ and $M_{{\eta }^{\prime }}$ meson in lattice QCD. The calculations are carried out on a set of 13 ETMC gauge ensembles with $N_f=2+1+1$…
