BCT Appendix AL2: Two-Loop Electron Mass — Technical Derivation

Key Points

• The central aim is to derive the electron mass using a two-loop approach within the BCT framework.
• Performed a two-loop calculation of the electron mass
• Executed a full instanton calculation
• Established a self-consistency chain for verification
• Conducted numerical verification to support the findings
• Successfully derived the electron mass using the BCT methodology
• Validation through instanton calculations confirmed accuracy
• Self-consistency and numerical methods corroborated results
