Higgs boson precision analysis of two-Higgs-doublet models: Full LHC Run 1 and Run 2 data
Abstract
We present the results obtained by performing global fits of two-Higgs-doublet models (2HDMs) using the full Run 1 and Run 2 Higgs datasets collected at the LHC. Avoiding unwanted tree-level flavor-changing neutral currents and including the wrong-sign cases, we consider 12 scenarios across six types of 2HDMs: Inert, type I, type II, type III, type IV, and Aligned 2HDMs. Our main results are presented in Table III and Fig. 1. We find that the type-I 2HDM provides the best fit, while the wrong-sign scenarios of the type-II and type-IV 2HDMs, where the normalized Yukawa coupling to down-type quarks is opposite in sign to the Standard Model (SM), are disfavored. We also observe that the Aligned 2HDM gives the second-best fit when the Yukawa couplings to down-type quarks take the same sign as in the SM, regardless of the sign of the Yukawa couplings to the charged leptons.
