Abstract
A search is presented for a heavy pseudoscalar boson A decaying to a Z boson and a Higgs boson with mass of 125GeV. 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 35.9fb-1 collected in 2016 by the CMS experiment at the LHC from proton–proton collisions at a center-of-mass energy of 13Te. 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 A boson mass range between 225 and 1000GeV.File | Dimensione | Formato | |
