221.1 τ+τ- production, process 221

This process provides predictions for the production of a tau lepton pair mediated by γ*∕Z, with subsequent leptonic decays. The calculation is available at LO only. The relevant matrix elements are adapted from the ones in ref. [1].

When removebr is true, the tau leptons do not decay.

221.2 Plotter

nplotter_auto.f is the default plotting routine.
