Description

Two-Higgs-doublet models (2HDM), {\em per se}, cannot predict the
values of the nonstandard scalar masses ($m_H, m_A$ and $m_+$).
However, assuming that a type-II 2HDM arises as an effective theory at
the electroweak scale from a supersymmetric ultraviolet (UV)
completion, where the quartic couplings of the 2HDM potential are
related to the gauge couplings of the Standard Model (SM), the ever
growing LHC Higgs boson data allow the {\em hitherto} unknown
nonstandard scalar masses to be almost uniquely determined from just
two input parameters: the supersymmetry breaking scale and $\tan\beta$
(the ratio of the two vacuum expectation values). We highlight some of
the salient features of this framework not emphasized previously in
the context of the Minimal Supersymmetric Standard Model (MSSM), and
make specific predictions on the masses and branching ratios of the
nonstandard scalars which can be probed by targeted experimental
searches. Our framework is valid even if the UV theory is not
supersymmetric but something else but unambiguously predicts the
scalar quartic couplings at the high scale.
