Search for a heavy pseudoscalar boson decaying to a Z boson and a Higgs boson at sqrt(s)=13 TeV

A search for a heavy pseudoscalar boson A decaying into a Z boson and the standard model Higgs boson is presented. In the considered final state, the Higgs boson decays to a b quark-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 $35.9~\mathrm{fb}^{-1}$ collected in 2016 by the CMS experiment at the CERN LHC from proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$. The data are found to be consistent with the background expectations. Exclusion limits are set in the context of two Higgs doublet models in the mass range between 225 and 1000 GeV.
