Massive and massless quark renormalization in QCD

Click For Summary
SUMMARY

The discussion focuses on the calculation of the renormalization constant for massive and massless quarks using the Modified Minimal Subtraction (MS) scheme and dimensional regularization. The author notes that their results align with each other, yet discrepancies exist in other literature. The conversation highlights the need for comprehensive resources, such as reviews or textbooks, that explicitly detail self-energy and vertex corrections in the context of MS renormalization.

PREREQUISITES
  • Understanding of Quantum Chromodynamics (QCD)
  • Familiarity with the Modified Minimal Subtraction (MS) scheme
  • Knowledge of dimensional regularization techniques
  • Basic concepts of renormalization in quantum field theory
NEXT STEPS
  • Research comprehensive reviews on MS renormalization techniques
  • Study self-energy calculations in Quantum Chromodynamics
  • Examine vertex corrections in quantum field theories
  • Explore discrepancies in literature regarding quark renormalization constants
USEFUL FOR

Physicists, particularly those specializing in Quantum Chromodynamics and quantum field theory, as well as researchers seeking to deepen their understanding of quark renormalization methods.

In modify minimal subtract sheme,using dimension regulation, I calculate the
the renormalization constant of massive quark and massless quark,get the same result.But in some papers,they are different.

Is there a review or any book on MS renormalization,that giving all the self energy and vetex correction explicitely? When read paper we can refere to it.
