Numbers are normalized to 10 $pb^{-1}$. Variations are given in the following as a number of events ($+, -, \pm$), not as a percentage!

Baseline Analysis

  • e10_medium OR mu10
  • 1e/0mu OR 0e/1mu
  • Lepton must match trigger ( el_EF_matched==1 or mu_muid_EF_matched==1 )
  • MET > 20 GeV
  • 4j20
  • bTag ( SV0>5.72 eff=50% )
