J/psi decays can produce ortho-dimuonium at a branching fraction of about 1.5e-12, while Upsilon decays allow tauonium production, with several channels potentially observable at planned facilities.
Retaining only the leading terms proportional to m4 J/ψ and m8 µ within the square brackets, the squared amplitude for the 3S1 state in Eq

Production of leptonium in heavy quarkonium decays
J/psi decays can produce ortho-dimuonium at a branching fraction of about 1.5e-12, while Upsilon decays allow tauonium production, with several channels potentially observable at planned facilities.
