  1. L1 EG2 efficiency on superclusters Clémentine Broutin, Alexandre Zabi, Pascal Paganini LLR – Ecole Polytechnique

  2. Keeping only SCspread on 1 or 2 TT

  3. Overview Run 132601 (good statistics, no timing scan, no EE energy features) • Look for L1 candidate in same L1 region as highest energy crystal in SC • Excluding masked regions (2.8% in EB, 5.4% in EE) • Timing cut for SC (excluding out‐of‐time spikes) (13.4% in EB, 2.8% in EE) • Excluding superclusters spread on more than 2 TT (17.3% in EB, 65.4% in EE) • Remove overall 33.3% of EB supercluster, 73.6% of EE superclusters Clémentine Broutin LLR -- Ecole Polytechnique

  4. Precisions • No double-counting of L1 candidates • for each event and each region, count only the highest ET supercluster • Efficiency as a funtion of the supercluster raw ET: • ET corrections are not adapted to low energy (what we are looking at for the moment) • In the endcaps, raw energy, like trigger primitive, does not take the preshower into account Clémentine Broutin LLR -- Ecole Polytechnique

  5. L1 EG2 efficiencyon superclusters • Look for L1 candidate in same L1 region as highest energy crystal in SC • Excluding masked regions (2.8% in EB, 5.4% in EE) • Timing cut for SC (excluding out‐of‐time spikes (13.4% in EB, 2.8% in EE) ) • Excluding superclusters spread on more than 2 TT(17.3% in EB, 65.4% in EE) • Remove overall 33.3% of EB superclusters, 73.6% of EE superclusters Run 132601 Clémentine Broutin LLR -- Ecole Polytechnique

  6. Back-up slides

  7. No cut on the number of TT

  8. L1 EG2 efficiencyon superclusters • Look for L1 candidate in same L1 region as highest energy crystal in SC • Excluding masked regions (2.8% in EB, 5.4% in EE) • Timing cut for SC (excluding out‐of‐time spikes (13.4% in EB, 2.8% in EE) ) • Remove overall 16.2% of EB superclusters, 8.2% of EE superclusters Run 132601 Clémentine Broutin LLR -- Ecole Polytechnique

  9. Same considerations,for SC belonging to electrons

  10. L1 EG2 efficiencyon electrons (EB) • Look for L1 candidate in same L1 region as highest energy crystal in SC • Excluding masked regions (3.4% in EB) • Timing cut for SC (excluding out‐of‐time spikes (5.4% in EB) ) • Remove overall 8.8% of EB superclusters Run 132601 Clémentine Broutin LLR -- Ecole Polytechnique

  11. L1 EG2 efficiencyon electrons (EB) • Look for L1 candidate in same L1 region as highest energy crystal in SC • Excluding masked regions (3.4% in EB) • Timing cut for SC (excluding out‐of‐time spikes (5.4% in EB) ) • Excluding superclusters spread on more than 2 TT(38% in EB) • Remove overall 46.8% of EB electrons Run 132601 Clémentine Broutin LLR -- Ecole Polytechnique
