Abstract
A search is presented for a heavy pseudoscalar boson $$\text {A}$$decaying to a Z boson and a Higgs boson with mass of 125$$\,\text {GeV}$$. 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$$\,\text {fb}^{-1}$$collected in 2016 by the CMS experiment at the LHC from proton–proton collisions at a center-of-mass energy of 13$$\,\text {Te}\text {V}$$. 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 $$\text {A}$$boson mass range between 225 and 1000$$\,\text {GeV}$$.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
