Large - Angle Two - Photon Exclusive Channels in Quantum
Detailed leading order QCD predictions are given for the scaling, angular, and helicity dependence of the reactions yy -f 6 (M=r, K, p, etc.) at large momentum transfer. In addition to providing a basic test of QCD at short distances, measurements can be used to determine the process-independent meson distribution amplitudes $M(x,Q). Other related two-photon channels such as yy+yp, y*y+rO, no, ...
متن کاملTwo-Photon Exclusive Processes in Quantum Chromodynamics*
QCD predictions for 77 annihilation into single mesons, meson pairs, and baryon pairs are reviewed. Two-photon exclusive processes provide the most sensitive and practical measure of the distribution amplitudes, and thus a critical confrontation between QCD and experiment. Both the angular distribution and virtual photon mass dependence of these amplitudes are sensitive to the shapes of the r$(...
متن کاملExclusive Two - Photon Processes in Quantum Chromodynamics
Leading order perturbative QCD predictions are given for the twophoton processes yy + ~71, 6, and pp at large momentum transfer. As we have shown in a series of recent papers,l the predictions of perturbative quantum chromodynamics can be extended to the whole domain of large momentum transfer exclusive processes. The results lead to a comprehensive new range of rigorous predictions of QCD whic...
متن کاملTests of Perturbative Quantum Chromodynamics in Photon - Photon Collisions
The production of hadrons in the collision of two photons via the process1 e+e-f e+e-X (see Fig. 1) can provide an ideal laboratory for testing many of the features of the photon's hadronic interactions, especially its short distance aspects. We will review here that part of two-photon physics which is particularly relevant to tests of perturbative QCD. (Invited talk presented at the 1979 Inter...
متن کامل. - Two Topics in Quantum Chromodynamics ”
The two topics are (1) estimates of perturbation theory coefficients for R (e+e+ hadrons), and (2) th e virtual-photon structure function, with emphasis on the analytic behavior in its squared mass.
