Description
The Two Higgs Doublet Model (2HDM) is one of the simplest and best motivated extensions of the Standard Model (SM), which expands the scalar sector. By introducing a second Higgs doublet, it provides new sources of CP violation that are relevant for baryogenesis and potential explanations for flavor anomalies observed in B-meson decays. In this model, the Yukawa couplings scale with the fermion masses, making the tau lepton a particularly sensitive probe to search for type extension of the SM.
In this work, we present a phenomenological study of the Type II 2HDM, performing a systematic exploration of the parameter space defined by the heavy scalar masses and the mixing parameter tanβ, while remaining consistent with the SM-like behavior of the observed 125 GeV Higgs boson. We incorporate theoretical constraints along with current experimental bounds from LHC searches and B-physics observables to delineate the allowed regions in parameter space. Using Monte Carlo simulations and machine learning techniques, we identify viable configurations and evaluate the discovery potential of additional Higgs states in τ-lepton final states. Our results highlight benchmark scenarios with heavy charged and neutral scalars that remain within reach of the current LHC and the future High-Luminosity LHC program.
