Two Higgs Doublets, a 4th Generation and a 125 GeV Higgs: A Review
Figure 2
(a) The allowed points in parameter space projected onto the 68%, 95%, and 99% CL contours in the - plane. (b) 95% CL allowed range in the plane. (c) Allowed region in the plane within the CL contour in the - plane. All plots are for any 2HDM setup (such as the 2HDMII and the three types of the 4G2HDM; see text) and with 100000 data points setting the light Higgs mass to GeV and varying the rest of the parameters in the ranges , , , , , , , , and and the CP-even neutral Higgs mixing angle in the range .
