New Phenomenology Paper

“Topping-up multilepton plus b-jets anomalies at the LHC with a Z’ boson“ , co-authored by A. Juste, together with T. Vazquez Schoeder and theorists E. Alvarez and M. Szewc, was recently submitted to the arXiv.
This paper studies several discrepancies in ttH and 4-tops searches at the LHC in multilepton plus b-jets final states, and develops a phenomenological New Physics model involving a Z’ boson that can account for them. This model provides a better fit to the experimental data than the Standard Model for a New Physics scale of approximately 500 GeV, and with a hierarchical coupling of the Z′ boson that favours the top quark and the presence of FCNC currents. It is also shown that the parameter space of the model that best fits the data could be probed with a significance exceeding 3 standard deviations with just the full Run-2 dataset.
