In the Two Higgs Doublet Model (2HDM), the exotic decay modes of a heavy non-SM Higgs decaying into two light Higgses or one Higgs with one SM gauge boson offer new discovery potential for non-SM Higgses. The latest CMS experimental search for neutral resonances decaying into a Z boson and a pair of b jets or tau leptons could be interpreted as H/A to ZA/ZH. In the original experimental paper, results in the mA vs. mH place for a given value of tan(beta) near alignment limit, or in the plane of tan(beta) vs. cos(beta-alpha) for fixed values of mA and mH were given for the type-II 2HDM. We reinterpret this experimental results in both Type-I and Type-II 2HDM, and consider benchmark scenarios of non-SM Higgs spectrum, as well as representative values of tan(beta), cos(beta-alpha), and soft Z2 breaking parameter m12.
