SUMMARY

The discussion focuses on determining the structure function F2 in the context of Quantum Chromodynamics (QCD) with R=0 at specific values of x and Q. The structure function can be derived from the cross-section, with an approximate formula of F2 ≈ [0.06 ± 6]/Q2. For further understanding, the discussion references the paper available at http://arxiv.org/pdf/0805.3116v2.pdf and R.G. Roberts' book "The Structure of the Proton" as essential resources for comprehensive insights into structure functions and proton properties.

PREREQUISITES
  • Understanding of Quantum Chromodynamics (QCD)
  • Familiarity with structure functions in particle physics
  • Knowledge of cross-section calculations
  • Basic grasp of Q2 dependence in high-energy physics
NEXT STEPS
  • Read R.G. Roberts' "The Structure of the Proton" for in-depth knowledge on proton structure functions
  • Study the paper at http://arxiv.org/pdf/0805.3116v2.pdf for advanced methodologies in deriving structure functions
  • Explore QCD models to understand the implications of R=0 on structure functions
  • Investigate the role of Q2 in high-energy particle interactions
USEFUL FOR

Particle physicists, researchers in high-energy physics, and students studying Quantum Chromodynamics will benefit from this discussion, particularly those focused on structure functions and proton properties.

hi
how can I determine structure function ## F_2## in ##R=QCD##, with having ##F_2## in ##R=0## in special ##x## and ##Q## ?
thanks
 
The structure function can be directly derived from the cross section if you have a an approximate idea of the value of R. I think it has a Q2 dependence to be exact but it can be approximated as about [0.06 +/- 6]/Q2 There are various papers on how to get these structure functions from other sources: http://arxiv.org/pdf/0805.3116v2.pdf and then there is R.G. Roberts "The Structure of the Proton" - pretty much THE handbook for information about any kinds of functions and properties relating to sub components of the proton.
