SUMMARY

The discussion centers on the absence of detected supersymmetric (SUSY) particles at the Large Hadron Collider (LHC) and its implications for theoretical physics. Participants agree that while the LHC has ruled out many models, it has not yet excluded most SUSY models, which remain viable due to a large parameter space. The conversation highlights the challenges faced by SUSY theorists in securing funding and the ongoing debate about the relevance of SUSY in explaining dark matter and gauge unification. Key points include the limitations of current experimental data and the need for further exploration as the LHC continues to accumulate data.

PREREQUISITES
  • Understanding of supersymmetry (SUSY) theories
  • Familiarity with the Large Hadron Collider (LHC) and its data accumulation
  • Knowledge of particle physics concepts such as gauge unification and dark matter candidates
  • Awareness of the hierarchy problem in theoretical physics
NEXT STEPS
  • Research the implications of the hierarchy problem in SUSY theories
  • Explore alternative models of new physics beyond the Standard Model
  • Investigate the role of SUSY in dark matter and its experimental constraints
  • Learn about the latest findings from the LHC regarding SUSY and other BSM physics
USEFUL FOR

Particle physicists, theoretical physicists, and researchers interested in the implications of SUSY and LHC findings on modern physics theories.

From what I gather, the "universality" of the three varieties of leptons is the real problem here. They are lumped together as a single type of entity when they each have their own composition and therefore variances in the mass each type starts out with. To expect them to all decay similarly seems quite curious. You can fire three bullets of different masses from the same rifle but you certainly would not expect all three to land at exactly the same location downrange. The "violations" would seem to be inherent due to the false assumption that they were all the same in the beginning.

That doesn't make any sense.
