The Virtual Photon Structure Functions and AdS/QCD Correspondence
نویسنده
چکیده
We study the virtual photon structure functions from gauge/string duality. If the Bjorken variable x is not small, supergravity approximation becomes good in dual string theory. We calculate the virtual photon structure functions at large ’t Hooft coupling in a moderate x-region and determine x-behavior of the structure functions. We also show that the Callan-Gross relation FL = 0 is satisfied to a good approximation in gravity calculation. E-mail address: [email protected]

Polarized and Unpolarized Structures of the Virtual Photon
As Maria Krawczyk remarked in her introductory talk on structure functions [1] , the virtual photon structure provides a unique test of QCD. In this talk I would like to discuss the polarized and unpolarized virtual photon structures. But because of the limitation of the allocated time, I will mainly focus my talk on the polarized virtual photon structure. Recently there has been growing intere...
متن کاملStructure Functions for the Virtual and Real Photons
Development of concepts related to the photon and its high energy hadronic interaction is briefly reviewed. A photon considered as an ideal probe of hadron structure, paradoxically is also considered as an ideal target to test the perturbative QCD. The present status of the theoretical and experimental analysis of the structure functions for a virtual and real photon is presented. 100 YEARS OF ...

KUNS-2121 YNU-HEPTh-07-103 The unpolarized virtual photon structure functions F γ 2 (x,Q , P ) and F γ L(x,Q , P ) are investigated in perturbative QCD for the kinematical region Λ ≪ P 2 ≪ Q, where −Q(−P ) is the mass squared of the probe (target) photon and Λ is the QCD scale parameter. In the framework of operator product expansion supplemented by the renormalization group method, the definit...

متن کاملPolarized Virtual Photon Structure Function in the Next-to-leading Order in QCD
The virtual photon structure function g 1 (x,Q , P ), which can be obtained in polarized ee colliding-beam experiments, is investigated for Λ ≪ P 2 ≪ Q, where −Q (−P ) is the mass squared of the probe (target) photon. The analysis is made to next-to-leading order in QCD, in the framework of the QCD improved parton model with the DGLAP evolution equations. The non-leading corrections significant...
