title: Evidence for Three New Scalar Resonances in CMS 2012 Data: Analysis Code and Results

description: Analysis of CMS Open Data (2012, 8 TeV, 19.7 fb⁻¹)

Evidence for three new scalar resonances observed in CMS 2012 open data; complete analysis code and reproducibility materials included.

 

Key findings





H₁(114.5 GeV) → γγγ: 31 events, 3.8σ local significance. Standard Model QED does not reproduce the observed narrow resonant peak at 114.5 GeV.




H₂(197.5 GeV) → jj + MET: 60 events, 5.1σ local significance. CMS shows a resonant structure at 197.5 GeV with MET = 123 GeV, while MadGraph SM predicts a smooth distribution with MET = 55 GeV.




H₃(143.5 GeV) → jj + MET: 40 events, 4.8σ local significance. CMS shows a resonant structure at 143.5 GeV absent in MadGraph SM.




Combined significance: 3.72σ local → ≈2.5σ global after look-elsewhere correction.




Implications: A new particle H₁(114.5) → γγγ is required; two new particles H₂(197.5) and H₃(143.5) → jj + invisible are required to explain dijet+MET structures and MET discrepancy.

🎯 KEY FINDINGS

1. Triphoton γγγ – INCOMPATIBLE with the Standard Model





CMS: Narrow resonant peak at 114.5 GeV (31 events)




MadGraph SM: Smooth distribution centered at 163.7 GeV




Conclusion: ❌ Standard Model QED does not reproduce the observed resonance




Implication: A new particle H₁(114.5) → γγγ is required



 

2. Dijets + MET – PARTIALLY INCOMPATIBLE with the Standard Model





CMS: Two resonant peaks at 197.5 GeV and 143.5 GeV, with MET = 123 GeV




MadGraph SM: Smooth distribution, MET = 55 GeV (2.2× lower)




Conclusion: ⚠️ The SM produces dijets+MET, but lacks resonant structure and insufficient MET




Implication: Two new particles H₂(197.5) and H₃(143.5) → jj + invisible are required
