158.1 QQ production, processes 157–159

These processes are calculable at leading LO and next-to-leading order NLO. These processes calculate the production of heavy quarks (157 for top, 158 for bottom and 159 for charm) up to NLO using the matrix elements of ref. [1]. No decays are included.

158.2 Plotter

nplotter_tt_tot.f is the default plotting routine.
