Abstract
We exhibit a method for simultaneously treating recoil and threshold correc tions in single-photon inclusive cross sections, working within the formali sm of collinear factorization. This approach conserves both the energy and transverse momentum of resummed radiation. At moderate p(T), we find the po tential for substantial enhancements from higher-order perturbative and pow er-law nonperturbative corrections.
