Anomalous magnetic moment of electron

introduction

• amplitude = sum of integrals = \(\sum_{n\text{ loops}}\) sum of integrals
• anomalous electron magnetic dipole moment 1.00115965219
• 11 digits match
• as n grows, number of Feynman diagrams grows exponentially
• integrals are becoming difficult

 

 

• correction terms

 

 

anamalous electron magnetic dipole moment

• In Dirac’s theory a point like spin 1/2 object of electric charge q and mass m has a magnetic moment\[\mathbf{\mu}=q\mathbf{S}/m\]
