Talk on QCD Calculations by Numerical Integration

Abstract

Calculations in Quantum Chromodynamics are typically performed using a method pioneered by Ellis, Ross and Terrano in 1981. In this method, one combines numerical integrations over the momenta of final state particles with analytical integrations over the momenta of virtual particles. I discuss a more flexible method in which one performs all of the integrations numerically.
