Higgcision in the two-Higgs doublet models

We perform global fits to general two-Higgs doublet models (2HDMs) with generalized couplings using the most updated data from ATLAS, CMS, and Tevatron. We include both scenarios with CP-conserving and CP-violating couplings. By relaxing the requirement on the discrete symmetries that are often imposed on the Yukawa couplings, we try to see which of the 2HDMs is preferred. We found that (i) Higgcision in 2HDMs can be performed efficiently by using only 4 parameters including the charged Higgs contributions to the Higgs couplings to two photons. (ii) the differences among various types of 2HDMs are very small with respect to the chi-square fits, (iii) tan beta is constrained to be small, (iv) the p-values for various fits in 2HDMs are worse than that of the strandard model. Finally, we put emphasis on our findings that future precision measurements of the Higgs coupling to the scalar top-quark bilinear (C-u(S)) and tan beta may endow us with the discriminating power among various types of 2HDMs especially when C-u(S) deviates from its SM value 1.
