Yukawa interaction and chirality.

Click For Summary
SUMMARY

The discussion centers on the Yukawa interaction and its implications for chirality in particle physics, specifically regarding how the Higgs vacuum expectation value (vev) couples opposite chiral fermions to form physical particles like electrons and positrons. It is established that the Yukawa interaction does not flip chirality or helicity, raising questions about how angular momentum is conserved in this context. The conversation highlights the complexity of these interactions and the need for clarity in understanding the coupling of chiral fields.

PREREQUISITES
  • Understanding of Yukawa interactions in quantum field theory
  • Familiarity with Higgs vacuum expectation value (vev)
  • Knowledge of chirality and helicity in particle physics
  • Basic concepts of angular momentum conservation in quantum mechanics
NEXT STEPS
  • Research the mathematical formulation of Yukawa interactions in quantum field theory
  • Study the role of the Higgs boson in particle mass generation
  • Explore the relationship between chirality, helicity, and angular momentum in massless particles
  • Examine case studies of fermion interactions and their implications for particle physics
USEFUL FOR

Particle physicists, quantum field theorists, and students studying the Standard Model who seek to deepen their understanding of fermion interactions and the role of the Higgs mechanism.

i still can't figure out how the higgs vev couples opposite chiral fermions(spinor components) to compose a physical electron/positron. (and actually in kurros 's thread it says that the yukawa interaction does not flip chirality nor helicity. what the hell does it mean for the yukawa interaction term making two terms that couple same chiral fields??). in that way how does it conserve angular momentum(since chirality and helicity is same in the massless limit...)??
