Description
We explore the decay properties of the isovector and isoscalar $1^{-+}$ light hybrids $\pi_1$ and $\eta_1$ $\pi_1$ in $N_f=2$ lattice QCD at a pion mass $m_\pi\approx 417~\mathrm{MeV}$. The McNeile and Michael method is adopted to extract the effective couplings in $N_f=2$ QCD for the decays.
The $N_f =3$ degenerate QCD result with physical mixing angle is also a partial quench result.
