The hadronic production of a W-boson and heavy quarks
R. Keith Ellis (Fermilab)

I present the results of a one-loop calculation of the production of a heavy quarks in association with a W-boson, retaining the mass for the heavy quark. Using a special choice for the heavy quark spinors we obtain analytic expressions for the one-loop amplitudes which are amenable to fast numerical evaluation. The full next-to-leading order (NLO) calculation of hadron + hadron → W(→ eν)b¯bwith massive b-quarks is included in the program MCFM. A comparison is performed with previous published work.
