| 113 | | |
| | 111 | * 3.1. Exactly 4 leptons |
| | 112 | * 3.2. 2 pairs of opposite sign |
| | 113 | * 3.3. At least one pair must have same flavour leptons |
| | 114 | * 3.4. We define Z1 = reconstructed Z from opposite-sign same-flavour pair the closest to the Z mass. We define Z2 = reconstructed Z from the other pair (same-flavour or not). |
| | 115 | * 3.5. Defining 4 signal regions according the final states: |
| | 116 | * 4l-DF-1b |
| | 117 | * 4l-DF-2b |
| | 118 | * 4l-SF-1b |
| | 119 | * 4l-SF-2b |
| | 120 | * 3.5. Cut on PT34 = scalar sum of the transverse momenta of the third and fourth leptons: |
| | 121 | * [4l-DF-1b]: PT34 > 35 GeV |
| | 122 | * [4l-SF-1b]: PT34 > 25 GeV |
| | 123 | * 3.6. MET: |
| | 124 | * 3.7. Number of b-jets: |
| | 125 | * [4l-DF-1b]+[4l-SF-1b]: #b-jets = 1 |
| | 126 | * [4l-DF-2b]+[4l-SF-2b]: #b-jets >= 2 |
