摘要
We report on QCD radiative corrections to the processes p (p) over bar-->W+2 jets and p (p) over bar-->Z+2 jets at the Fermilab Tevatron. These processes are included in the Monte Carlo program MCFM, which allows the calculation of any infrared finite variable at next-to-leading order. Because of a better theoretical description of jets at next-to-leading order, some distributions exhibit significant corrections. As expected, the unphysical dependence of theoretical predictions upon the renormalization and factorization scales is greatly reduced compared to leading order. As an example of the predictions that may now be made with MCFM, we present a next-to-leading order estimate of the heavy flavor content of jets produced in association with vector bosons.
