In this talk, we discuss the new physics implication in Two Higgs doublet Model (2HDM) under various experimental constraints. As part work of Gambit group, our work is to use the global fit method to constrain the parameter space, find out the hints for new physics and try to make some predictions for further studies.

In our global fit, we include the constraints from LEP, LHC (SM-like Higgs boson search), the theoretical requirements ( Unitarity, Perturbativity, and vacuum stability), various flavour physics constraints ( radiative B Decay $B \to X_s \gamma$, rare fully leptonic B decays $B \to \mu^+\mu^-$ ,etc) and muon g-2 anomaly.

After the 7-parameter global fit, we have a detailed study about the result, analysing individual constraints effects, finding out advantages of every constraint in constraining parameters and discovering new particles. For the Type-II 2HDM, we find that the $\lambda_2$ is sensitive to the LHC SM-lkie Higgs boson search results. Our final results will be displayed in $\tan \beta$ - $\cos(\beta-\alpha)$, $m_A$ - $\tan \beta$, which are usually considered.
