Space-time properties of the higher twist amplitudes
نویسندگان
چکیده
A consistent and intuitive description of the twist-4 corrections to the hadron structure functions is presented in a QCD-improved parton model using timeordered perturbative theory, where the collinear singularities are naturally eliminated. We identify the special propagators with the backward propagators of partons in time order. PACS numbers: 12.38.Bx, 13.85.Qk, 11.15.Bt

A geometric higher twist effect on nuclear target
The higher twist effects in deep inelastic scattering on the nuclear target are studied using time ordered perturbation theory. We showed that the collinear rescattering of the outgoing quark on the extra nucleons via the contacting gluon-pair is dominant in nuclear size-dependent effects. The Qiu-Vitev resummation is proved by using the geometric properties of the higher twist amplitudes. The ...

Ab initio calculation at HF/6-31G* level of theory for geometry optimization and MP2/6-31G*//HF/6-31G* for a single point total energy calculation are reported for the important energyminimumconformations and transition-state geometries of of cyclodeca-1,2,3-triene (1). The mostfavorable conformation of 1 is a unsymmetrical twist-chair (1-TC) structure. Degenerateinterconversion of 1-TC with it...
متن کاملHigher Twist Distribution Amplitudes of the Nucleon in QCD
We present the first systematic study of higher-twist light-cone distribution amplitudes of the nucleon in QCD. We find that the valence three-quark state is described at small transverse separations by eight independent distribution amplitudes. One of them is leading twist-3, three distributions are twist-4 and twist-5, respectively, and one is twist-6. A complete set of distribution amplitude...
متن کاملTwist decomposition of nonlocal light-ray operators and harmonic tensor functions
Light–cone(LC) dominated hard scattering processes, like deep inelastic scattering and deeply virtual Compton scattering, and various hadronic wave functions, e.g., vector meson amplitudes, appearing in (semi) exclusive processes are most effectively described by the help of the nonlocal light–cone expansion [1].Thereby, the same nonlocal LC–operator, and its anomalous dimension, is related to ...
