VBF Jet Selection Criteria for Efficient High Energy Physics Data Analysis

This analysis outlines the stringent selection criteria for the Very Forward Backward (VBF) jets, focusing on parameters such as pTjet, mjj, ηjet1, ηjet2, and |Δη|. Understanding the efficiency impact due to jet loss, specifically in scenarios involving interaction with the Hadronic Forward (HF) section, is crucial for accurate data interpretation and results in high mjj values.

  1. Both VBF jets in HBHE Pass HT Seed!  HB HE HE HF HF L1_ETM40 L1_HTT{150,175,200} HLT: pTjet>35, mjj>700, ηjet1xηjet2<0, |Δη|>3.5

  2. One VBF jet lost to HF  Pass MET Seed!  (HF not used at L1) HB HE HE HF HF L1_ETM40 L1_HTT{150,175,200} HLT: pTjet>35, mjj>700, ηjet1xηjet2<0, |Δη|>3.5

  3. Both VBF jets lost to HF Fail L1 (HF not used at L1) HB HE HE HF HF L1_ETM40 L1_HTT{150,175,200} HLT: pTjet>35, mjj>700, ηjet1xηjet2<0, |Δη|>3.5

  4. You can see this in the efficiency fall off at |Δη|>6.0 (both jets must be in HF here). This also corresponds to large mjjsince mjj~sqrt(pTjet1pTjet2) e|Δη|
