Abstract We consider processes which produce final state hadrons whose energy is much greater than their mass. In this limit interactions involving collinear fermions and gluons are constrained by a symmetry, and we give a general set of rules for constructing leading and subleading invariant operators. Wilson coefficients C(μ, P ) are functions of a label operator P , and do not commute with collinear fields. The symmetry is used to reproduce a two-loop result for factorization in B → Dπ in a simple way.
