Phys. Rev. Lett. 62, 2229–2232 (1989)Absence of Sudakov factors in large-angle photoproduction and Compton scatteringReceived 16 March 1989; published in the issue dated 8 May 1989 We show that lowest-order predictions for large-angle Compton scattering and photoproduction are not sensitive to Sudakov corrections. As a result, the asymptotic amplitudes for these processes, including their absolute normalizations and phases, should be given by lowest-order calculations, without a resummation of perturbation theory. © 1989 The American Physical Society URL:
