In this thesis, I present a next-to-leading-order (NLO) calculation for the production of two jets, at least one of which contains a charm quark, which is an important background to single-top production. I discuss the leading order results and their scale dependence before outlining the difficulties of an NLO calculation, and the need for treating the charm quarks as massive in a few areas of the calculation. The NLO corrections turn out to be rather modest, but taking the calculation to NLO greatly improves scale uncertainty. |
