Search for a heavy pseudoscalar boson decaying to a Z and a Higgs boson at root s=13TeV
A search is presented for a heavy pseudoscalar boson A decaying to a Z boson and a Higgs boson with mass of 125 GeV. In the final state considered, the Higgs boson decays to a bottom quark and antiquark, and the Z boson decays either into a pair of electrons, muons, or neutrinos. The analysis is...

| Summary: | A search is presented for a heavy pseudoscalar
boson A decaying to a Z boson and a Higgs boson with
mass of 125 GeV. In the final state considered, the Higgs
boson decays to a bottom quark and antiquark, and the Z
boson decays either into a pair of electrons, muons, or neutrinos. The analysis is performed using a data sample corresponding to an integrated luminosity of 35.9 fb−1 collected
in 2016 by the CMS experiment at the LHC from proton–
proton collisions at a center-of-mass energy of 13 TeV. The
data are found to be consistent with the background expectations. Exclusion limits are set in the context of two-Higgsdoublet models in the A boson mass range between 225 and
1000 GeV. |
