Heavy flavor inW+ jets production at the Fermilab Tevatron

This note describes a theoretical study of $Wb\overline{b}$ and $Wjj$ final states at the Tevatron using the NLO program MCFM. We extensively study the effect of NLO corrections with respect to variations of input parameters such as the minimum jet $p_T$ and the choice of renormalization and factorization scales. In particular, we examine possible implications for the Method 2 QCD background subtraction technique for $t\overline{t}$ production.
