Abstract
So far, we have only considered processes which involve large energy flows in two directions, such as the Sudakov form factor or the inclusive Drell-Yan cross section. However, many processes involve multiple directions of large energy flow. These include collider processes with several jets of energetic particles in the final state. In this section, we will discuss the effective theory relevant for observables which involve n directions of large energy flow.
