Standard Model Anomalies: right-handed neutrinos

Click For Summary

Discussion Overview

The discussion revolves around the concept of right-handed neutrinos within the context of the Standard Model (SM) of particle physics, specifically focusing on anomalies and hypercharge assignments. Participants explore theoretical implications, potential solutions, and resources for further reading on the topic.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that considering right-handed neutrinos could lead to more anomaly-free solutions than hypercharge for a U(1) gauge group.
  • Another participant references a specific paper that may provide insights into the topic, indicating a connection to existing literature.
  • There is a mention of B-L (baryon number minus lepton number) conservation as a potential aspect of the discussion.
  • A question is raised about whether assigning one hypercharge to a field would determine the values of all other hypercharges and if this is predicted by a single anomaly-free solution.
  • A request for recommendations on textbooks addressing open problems in the Standard Model is made, indicating a desire for further exploration of the topic.

Areas of Agreement / Disagreement

The discussion includes multiple competing views and remains unresolved, particularly regarding the implications of right-handed neutrinos and hypercharge assignments.

Contextual Notes

Participants express uncertainty about subscriptions to specific journals and papers, which may limit access to detailed discussions or solutions. There are also unresolved questions regarding the nature of hypercharge assignments and their relationship to anomaly-free solutions.

Who May Find This Useful

This discussion may be of interest to those studying particle physics, particularly in the areas of the Standard Model, neutrino physics, and theoretical anomalies.

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.
