This calculation is based on matrix elements for \\nu e e+ \\mu- \\bar{\\nu}_{\\mu}b\\bar{b} production and includes all non-resonant diagrams, interferences, and off-shell effects of the top quarks. Such contributions are formally suppressed by the top-quark width and turn out to be small in the inclusive cross section.
