This calculation is based on the matrix elements for the $e^+ \\nu_e\\, \\mu^-\\bar{\\nu}_\\mu\\, b\\bar{b} \\,\\tau^+\\tau^-$ final state and includes all resonant and non-resonant Feynman diagrams, interferences and off-shell effects of the top quark as well as the $W$ and $Z$ gauge bosons. Also incorporated are photon-induced contributions.
