Exotic hybrid mesons in hard electroproduction
We estimate the sizeable cross section for deep exclusive electroproduction of an exotic J = 1 hybrid meson in the Bjorken regime. The production amplitude scales like the one for usual meson electroproduction, i.e. as 1/Q. This is due to the non-vanishing leading twist distribution amplitude for the hybrid meson, which may be normalized thanks to its relation to the energy momentum tensor and ...

متن کاملHard Electroproduction of Vector Mesons
In this talk I am going to report on an ongoing analysis [1, 2, 3] of hard electroproduction of light vector mesons within the handbag approach which is based on QCD factorization into hard subprocesses and generalized parton distributions (GPDs) encoding the soft, nonperturbative physics. As is well-known the leading-twist contribution (i.e. employing the collinear approximation) evaluated to ...
متن کاملHard diffractive electroproduction of vector mesons in QCD.
Hard diffractive electroproduction of longitudinally polarized vector mesons is calculated within the leading αs ln Q2 ΛQCD approximation of QCD using the leading order parton densities within the nucleon. Novel QCD features of the production of excited states and of the restoration of flavor symmetry are analyzed. At the onset of the asymptotic regime, our analysis finds an important role of q...
متن کاملFactorization for hard exclusive electroproduction of mesons in QCD
We formulate and prove a QCD factorization theorem for hard exclusive electroproduction of mesons in QCD. The proof is valid for the leading power in Q and all logarithms. This generalizes previous work on vector meson production in the diffractive region of small x. The amplitude is expressed in terms of off-diagonal generalizations of the usual parton densities. The full theorem applies to al...
