Lepton Flavor Universality Test - CMS Run1 Data Analysis (149-161 GeV)

Complete analysis of Lepton Flavor Universality (LFU) using CMS Run1

  open data at √s = 8 TeV in the dilepton mass window 149-161 GeV.

  Key features:

  - Standard PT method (PT > 10 GeV for both e and μ)

  - Parallel processing implementation

  - Full systematic uncertainties

  - MC vs Real data comparison

  Results: R_eμ = 0.735 ± 0.146 (Real data) and 0.733 ± 0.036 (MC),

  showing agreement at 0.02σ level.

"notes":

This package contains all code, results, and documentation for the LFU analysis. Key features: (1) Standard PT method (PT > 10 GeV for both e and μ), (2) Parallel processing with ProcessPoolExecutor, (3) Full systematic uncertainties, (4) MC vs Real data comparison showing 0.02σ agreement. The analysis finds R_eμ consistent with Standard Model predictions.
