Virtual photon structure functions to the next-to-next-to-leading order in QCD
We investigate the unpolarized virtual photon structure functions F 2 x;Q2; P2 and F L x;Q2; P2 in perturbative QCD for the kinematical region 2 P2 Q2, where Q2 ( P2) is the mass squared of the probe (target) photon and is the QCD scale parameter. Using the framework of the operator product expansion supplemented by the renormalization group method, we derive the definite predictions for the mo...
متن کاملThe Virtual Photon Structure to the Next-to-next-to-leading Order in QCD
We investigate the unpolarized virtual photon structure functions F γ 2 (x,Q 2, P 2) and F γ L(x,Q 2, P 2) in perturbative QCD for the kinematical region Λ2 ≪ P 2 ≪ Q2, where −Q2(−P 2) is the mass squared of the probe (target) photon and Λ is the QCD scale parameter. Using the framework of the operator product expansion supplemented by the renormalization group method, we derive the definite pr...
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...
متن کاملNext-to-next-to-leading order QCD analysis of DIS structure functions
It is performed for the first time a next-to-next-to-leading order analysis of deep inelastic structure functions F2 and FL using the recently determined first moments of the non-singlet anomalous dimensions and the corresponding Wilson coefficients. From a comparison to BCDMS data we found a slight decrease in the energy scale of perturbative QCD with respect to the next-toleading order analys...
متن کاملMulti-Photon Amplitudes for Next-to-Leading Order QCD
We present the tree-level amplitudes involving one, two and three photons that are required for next-to-leading order QCD calculations of production rates of three final-state particles. We also present the required one-loop amplitudes in terms of previously published results.
