SUMMARY

The absence of a little Higgs at Fermilab's Tevatron, which has not detected Higgs bosons below 130 GeV, raises questions about the viability of Supersymmetry (SUSY) as an explanation for electroweak (EW) scale breaking. While SUSY models suggest a little Higgs is necessary for this phenomenon, the Tevatron's current limitations, with expected reach only up to 120 GeV, do not definitively rule out SUSY. The discussion emphasizes the 95% confidence level regarding the detection of the little Higgs, indicating a remaining 5% possibility that it could still be observed. Clarification is needed on whether the discussion refers to the little Higgs or the lightest Higgs in the Minimal Supersymmetric Standard Model (MSSM).

PREREQUISITES
  • Understanding of Supersymmetry (SUSY) models
  • Knowledge of electroweak (EW) scale breaking
  • Familiarity with Higgs boson energy thresholds
  • Awareness of Fermilab's Tevatron capabilities and limitations
NEXT STEPS
  • Research the implications of Higgs boson mass limits in SUSY models
  • Study the role of the Minimal Supersymmetric Standard Model (MSSM) in particle physics
  • Explore the detection methods and technologies used at Fermilab's Tevatron
  • Investigate the significance of the LEP limit of 114.4 GeV in relation to Higgs searches
USEFUL FOR

Particle physicists, researchers in theoretical physics, and students studying Supersymmetry and Higgs boson research will benefit from this discussion.

To date, the little higgs implied by some SUSY models requires higgs of energies less than 130 GEV, which Fermilab's Tevatron has not yet seen.

These models do help explain EW breaking, however,

If SUSY explains E-w scale breaking, does it require a little Higgs at Tevatron energies?

I recognize it is only 95% so there is still a 5% chance it should see it, but does not seeing a little Higgs at Tevatron rule out SUSY as an explanation of EW scale breaking, with 95% confidence?

Do you mean little Higgs or the lightest higgs in the MSSM?

Either way, I don't think that the Tevatron has reached the LEP limit of 114.4 GeV yet. And I don't think that 130 GeV is reachable---I think they expect to reach 115 or 120 GeV by the time the thing shuts down and they analyze all of the data. (I'm just recalling numbers here, but I think this is right.)
