Abstract:
Based on a number of features from proton-proton collisions taken during data Run 1 data taking period at the LHC, a boson H, with a mass around the EW scale was postulated such that a significant fraction of its decays would entail the Standard Model (SM) Higgs boson and an additional scalar, S. One of the phenomenological implications of a simplified model, where S is treated a SM Higgs boson, is the anomalous production of high transverse momentum leptons. A combined study of Run 1 and Run 2 data are indicative of very significant discrepancies between data and SM Monte Carlos in a variety of final states involving multiple leptons with and without b-quarks. These discrepancies appear in corners of the phase-space where different SM processes dominate, indicating that the potential mis-modeling of a particular SM process is unlikely to explain them. Systematic uncertainties from the prediction of SM processes evaluated with currently available tools seem unable to explain these discrepancies away. The process H—>Sh contaminates the production of the SM Higgs boson at the LHC. Deviations from SM predictions in the current Higgs boson data at the LHC and the implications on future Higgs factories will be discussed
