Implication

Calculation of two-loop renormalization constants for fermion and gluon fields, suggesting methodological implications.

Key Points

  • The study calculates contributions to two-loop renormalization constants for fermion masses and coupling constants, impacting high-energy physics.
  • Important results include the beta functions derived from both the naive dimensional regularization and the Breitenlohner--Maison--'t~Hooft--Veltman schemes.
  • Utilizing the gamma_5 matrix, we perform detailed computations necessary for understanding renormalization group equations.
  • This approach may enable further refinement of theoretical models in quantum field theory and high-energy particle physics.
