Applicability of perturbative quantum chromodynamics to high-pt exclusive scattering

    Research output: Contribution to journalArticlepeer-review


    Relations among high-pt exclusive cross sections, particularly for γγ→baryon-antibaryon and for meson-nucleon scattering, test the applicability of perturbative QCD in the kinematic regime of the experiments. This permits assessment of the importance of higher-order corrections and non-leading-twist contributions to the Born approximation, the extent of the "Sudakov suppression," and the validity of the asymptotic approximation to the wave functions.
