Non-Pertubative Correction to R=σL/σT Due to the Effect of the QCD Vacuum Condensates

  •  Institute of Particle Physics,Hua-Zhong Normal University,Wuhan 430070

  • The effects of QCD vacuum condensate on hardron structure function are considered.Based on the background field theory,starting from the effective lagrangian of QCD we calculate the non-perturbative correction to ratio R=σL/σT of the hardron structure function.Our corrections are sensitive at small x regions.

Abstract: The effects of QCD vacuum condensate on hardron structure function are considered.Based on the background field theory,starting from the effective lagrangian of QCD we calculate the non-perturbative correction to ratio R=σL/σT of the hardron structure function.Our corrections are sensitive at small x regions.
