We investigate the impact of electroweak (EW), scalar and QCD corrections to the full set of decay branching ratios of an additional CP-even Higgs boson (H) in the two Higgs doublet model with a softly broken Z 2 symmetry. We employ the improved gauge independent on-shell scheme in the renormalized vertices. We particularly focus on the scenario near the alignment limit in which couplings of the discovered 125 GeV Higgs boson (h) coincide with those of the standard model while the Hhh coupling vanishes at

We calculate radiative corrections to decay rates of CP-odd Higgs boson A for various decay modes in the four types of two Higgs doublet models with the softly broken discrete Z 2 symmetry. The decay branching ratios are evaluated at the next-to-leading order for electroweak corrections and the next-to-next-to-leading order for QCD corrections. We comprehensively study the impact of the electroweak corrections on the decay rates and the branching ratios. We find that the radiative corrections can sizably modify the branching ratios, especially for the A → Zh decay mode in the nearly alignment scenario, where coupling constants of the SM-like Higgs boson h are close to those in the standard model. We also show correlations between the branching ratios of A and the scaling factor of the SM-like Higgs boson coupling including higher-order corrections. In addition, we show characteristic predictions on the decay pattern depending on the types of the Yukawa interaction, by which we can discriminate the types of the Yukawa interaction in future collider experiments.

“…The general or type-III 2HDM has been shown to be able to explain the flavour changing charged current for 𝑅(𝐷), whilst respecting constraints from the lepton flavour violating (LFV) decays 𝜏 → 𝜇𝛾 and 𝜏 → 3𝜇 [32]. The 2HDM may also provide an explanation for things such as LHC data [33][34][35][36][37], B-anomalies [38][39][40][41][42], and decays of Higgs bosons [43][44][45][46][47][48][49][50][51], to name a few.…”

GM2Calc is a leading tool for calculating precise contributions to 𝑎 𝜇 in the Minimal Supersymmetric Standard Model. In this proceeding we detail GM2Calc version 2 where it is extended so it can calculate two-loop contributions to 𝑎 𝜇 in the Two-Higgs Doublet Model (2HDM), based on the work in Ref. [1]. The 2HDM is a simple model, yet it is one of the few single field extensions of the Standard Model which is able to explain the muon 𝑔 − 2 anomaly. We demonstrate the powerful and flexible 2HDM capabilities of GM2Calc2, which include the most precise contributions in the literature and allow the user to work in their favourite type of the 2HDM as well as use complex and lepton flavour violating couplings. With its multiple interfaces and input flexibility, GM2Calc2 is a powerful tool both as a standalone code and as part of a larger code toolchain.
