    11 diphotons
     11Search for new physics n events with at least 3 electrons or muons and jets. Results are based on 35.9 fb^-1^ Luminosity at 13 TeV collected by CMS. Events are classified according to the number of b jets, missing transverse momentum, hadronic transverse energy, and the invariant mass of opposite-charge, same-flavor dilepton pairs. Exclusion limits are set for 4 different simplified SUSY models with gluino or 3^rd^ gen. squarks pair production.

    2626=== 3.1 Trigger selection ===
    2727
     28Trigger selections target di- and multilepton events.
     29
     30One trigger set requires:
     31* The two leptons required to meet the loose isolation criteria
     32* Leading lepton has pT > 23 GeV
     33* Sub-leading lepton has pT > 8 (12) GeV in the case of muons (electrons)
     34
     35Second set of triggers requires:
     36* pT > 8 GeV for both leptons
     37* HT (hadronic activity) > 300 GeV
     38
    2839PS: This part cannot usually be described by the fast-simulation of detector.

     42
     43* Jets:
     44   * clustered with anti-kt algorithm with Delta R = 0.4
     45   * pT > 30 GeV
     46   * | eta | < 2.4
     47
     48* B-jets:
     49   * b-tag efficiency 70%
     50   * misidentification probability of 10% and 1% is for c- and light-flavor jets, respectively.
     51   * pT > 25 GeV & | eta | < 2.4
     52
     53* Hadronic activity
     54   * HT  = Sum pt of the jets where all jets have pt > 30 GeV
     55
     56* Muon: | eta | < 2.4
     57
     58* Electrons: | eta | < 2.5
