SUMMARY

The 331 Model, represented as SU(3)c × SU(3)L × U(1), is a theoretical framework in particle physics that aims to address issues such as the quantization of electric charge and the three-generation problem of quarks and leptons. This model extends the Standard Model and proposes solutions to phenomena like proton decay. Additionally, it is compared with other grand unified theories like SU(5) and SU(10), which also attempt to resolve similar puzzles in particle physics.

PREREQUISITES
  • Understanding of the Standard Model of particle physics
  • Familiarity with group theory in physics
  • Knowledge of quantum field theory
  • Basic concepts of gauge symmetries
NEXT STEPS
  • Research the implications of the 331 Model on proton decay
  • Study the differences between SU(3)c × SU(3)L × U(1) and SU(5) models
  • Explore the three-generation problem in particle physics
  • Learn about gauge theories and their role in unifying forces
USEFUL FOR

Particle physicists, theoretical physicists, and researchers interested in advanced models beyond the Standard Model, particularly those focusing on charge quantization and generation problems.

Please tell me what is SU(3)cXSU(3)LXU(1)X model, and how to quantize electric charge, because I hear that they can do this quantization based on 331 model. Please help me, I am eagerly to know it.
With my best wishes and regard.

Please help me:three generation problem

I hear that some model example: SU(5), SU(10) solve many puzzle as quantization of charge
,proton decay, But I wonder whether those beyond standard model can solve the problem of
three quark-lepton generations or not.
Thanks very much for your help.
