50 f(-p₁) + f(-p₂) → Z(→ e^-(p₃) + e⁺(p₄)) + b(p₅) + b(p₆), (massive b-quarks)

50.1 Z + bb production, m_b≠0, process 50

These processes represent the production of a Z boson (or virtual photon) which subsequently decays leptonically, in association with a bb pair. The effect of the bottom quark mass is included throughout the calculation. The calculation may be performed at LO only, because the one-loop calculation with massive quarks has not yet been performed.

When removebr is true, the Z boson does not decay.

50.2 Plotter

nplotter_auto.f is the default plotting routine.
