Abstract: Using a 19.5 \textrm{fb$^{-1}$} data sample at $\sqrt{s} = 8$\TeV collected by the CMS experiment at the LHC,a search for an extension of the Higgs sector to Two Higgs Doublet Models is presented. Decays $H \rightarrow hh$ and $A \rightarrow Zh$ of the heavy scalar and pseudo-scalar Higgs bosons, respectively, include the Standard Model-like Higgs $h$ in the final state and lead to events with isolated leptons and photons. Observed multilepton events with or without diphoton candidates are organized into exclusive search channels based on event kinematics. The search channels are ordered by the amount of expected Standard Model background. Data-based estimation of the Standard Model backgrounds is emphasized, but data-validated simulations are also employed as appropriate. Observations are consistent with the Standard Model and lead to the exclusion of significant portions of Two Higgs Doublet Model parameter space presented in terms of the relevant parameters of the model. | ||
