Abstract:
The multi-lepton anomalies, i.e. deviations from the Standard Model predictions in LHC analyses with two or more leptons in the final state (with and without additional jets)point towards electroweak scale new physics. In particular, there are strong tensions in differential top quark distributions which could be explained by the associated production and decay of new Higges. Interestingly, the preferred mass range is compatible with the hint for narrow resonances at 95 GeV and 152 GeV with significances of 3.8 sigma and 4.9 sigma, respectively.
