Identical particle and lepton mass effects in the decay $H\to Z^{\ast }(\to {\tau }^{+}{\tau }^{-})+Z^{\ast }(\to {\tau }^{+}{\tau }^{-})$

We consider identical particle and lepton mass effects in the cascade decay $H\to Z^{\ast }(\to {\tau }^{+}{\tau }^{-})+Z^{\ast }(\to {\tau }^{+}{\tau }^{-})$. Since the scale of the problem is set by the off-shellness $…
