Book excerpt: The challenging problem of applicability of the perturbative QCD to exclusive processes is revealed. The basic ingredients both of the asymptotic large Q2 analysis and of the QCD sum rule approach are analyzed for the simplest and most well-studied example of the pion electromagnetic form factor. The main conclusion is that for accessible energies and momentum transfers the soft (nonperturbative) contributions dominate over those due to the hard quark rescattering subprocesses.

Book excerpt: From a data sample of 5.8 x 106 J/psi's collected by the MARK III detector at the storage ring SPEAR at SLAC, two-body decay modes of the J/psi into a vector and a tensor meson have been measured. From the studies of the tensor meson, recoiling against the ideally mixed and well understood vector mesons, quark correlations are established and compared with the theoretical expectations of the J/psi decays and the SU(3) predictions. The beginnings of a similar systematic study of the two-body vector scalar decays are also presented.

Available in PDF, EPUB and Kindle. Book excerpt: The long-standing problem of the applicability of perturbative QCD to hadronic elastic form factors is discussed. The basic ingredients both of the asymptotic large-Q2 treatment and of the QCD sum rule approach are analyzed. The main conclusion is that for accessible energies and momentum transfers the soft (nonperturbative) contributions dominate over those due to the hard quark rescattering subprocesses.
