Abstract:

This note details the search for a CP-even (H) and a CP-odd (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 two-Higgs-doublet-model with twisted custodial symmetry, leading to a mass triplet

\mathrm{m_{H^\pm}\sim m_H}

, and low-mass 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 center-of-mass energy.

Note:
