Renormalization Scheme Dependence of Vevs

Click For Summary
SUMMARY

The one-loop corrected vacuum expectation value (VEV) of a field is dependent on the renormalization scheme used. The discussion confirms that while certain parameter choices may cancel out in the fully summed answer, the initial selection of parameters is crucial. This indicates that the renormalization scheme plays a significant role in determining the VEV, contradicting the notion of independence.

PREREQUISITES
  • Understanding of quantum field theory concepts
  • Familiarity with renormalization techniques
  • Knowledge of vacuum expectation values (VEVs)
  • Basic grasp of one-loop corrections in particle physics
NEXT STEPS
  • Research different renormalization schemes in quantum field theory
  • Study the implications of one-loop corrections on VEVs
  • Explore parameter selection methods in renormalization
  • Investigate the fully summed answers in quantum field calculations
USEFUL FOR

The discussion is beneficial for theoretical physicists, quantum field theorists, and researchers focusing on particle physics and renormalization techniques.

Is the one-loop corrected vacuum expectation value of a field renormalization scheme independent?

No. since you need to choose parameters. The choices cancel only in the fully summed answer.
