Standard Model Anomalies: right-handed neutrinos

Click For Summary
SUMMARY

The discussion centers on the implications of right-handed neutrinos in the context of anomaly-free solutions within the Standard Model (SM) of particle physics. Participants reference the paper "Anomaly-Free U(1) Gauge Symmetries" (Phys. Rev. D 88, 116008) and the arXiv preprint (arXiv:1309.1709) to explore the relationship between hypercharge assignments and B-L conservation. The conversation highlights the need for a comprehensive understanding of how hypercharges influence each other and the existence of anomaly-free solutions in the SM framework.

PREREQUISITES
  • Understanding of the Standard Model of particle physics
  • Familiarity with U(1) gauge symmetries
  • Knowledge of hypercharge assignments and their implications
  • Basic grasp of B-L (Baryon minus Lepton) conservation principles
NEXT STEPS
  • Read "Anomaly-Free U(1) Gauge Symmetries" (Phys. Rev. D 88, 116008)
  • Explore the arXiv preprint (arXiv:1309.1709) for deeper insights
  • Investigate the role of hypercharge in anomaly cancellation
  • Find textbooks discussing open problems in the Standard Model
USEFUL FOR

Particle physicists, theoretical physicists, and researchers interested in the implications of right-handed neutrinos and anomaly-free solutions in the Standard Model.

If we consider de right-handed neutrino there would be more anomaly-free solutions than hypercharge for a U(1)?
 
Physics news on Phys.org
I am not suscribed :s
 
GIves you a starting point to search though.
 
B-L conservation?
 
Thank you.

If we would assign one hypercharge to a field that would determine the value of all others hypercharges? Are those predicted, also, by only one anomaly-free solution?
 
If you guys could tell me a good textbook about the open problems in SM I would be very grateful.
