Explicit Proof that Electroproduction of Transversely Polarized Vector Mesons Vanishes in Perturbative QCD
arXiv:hep-ph/0108214 · doi:10.1103/PhysRevD.65.077501
Abstract
By means of an explicit one-loop calculation, it is shown that the leading twist contribution to the exclusive electroproduction of transversely polarized vector mesons from the nucleon vanishes. This confirms the all-orders proof by Collins and Diehl.
