Abstract:
This note details the search for a CPeven (H) and a CPodd (A) Higgs bosons through the experimental signature of the process $ \mathrm{pp} \rightarrow \mathrm{H} \rightarrow \mathrm{ZA} \rightarrow \mathrm{l}^+\mathrm{l}^\mathrm{b\overline{b}} $. The theoretical context is a twoHiggsdoubletmodel with twisted custodial symmetry, leading to a mass triplet $ \mathrm{ m_{H^\pm} \sim m_H }$ , and lowmass pseudoscalar A. The hypothesis of Type II Yukawa couplings is considered. The search exploits an integrated luminosity of 2.3 fb$^{1}$ collected in 2015 by the CMS experiment at 13 TeV centerofmass energy.
