In this paper we show how gauge symmetries in an effective theory can be used to simplify proofs of factorization formulas in highly energetic hadronic processes. We use the soft-collinear effective theory, generalized to deal with back-to-back jets of collinear particles. Our proofs do not depend on the choice of a particular gauge, and the formalism is applicable to both exclusive and inclusive factorization. As examples we treat the π-γ form factor (γγ*→π0), light meson form factors (γ*M→M), as well as deep inelastic scattering (e-p→e-X), the Drell-Yan process (pp→Xl+l-), and deeply virtual Compton scattering (γ*p →γ(*)p).
