## Abstract

Results are reported on a search for decays of a pseudoscalar A boson into a Z boson and a light scalar h boson, where the Z boson decays into a pair of oppositely-charged electrons or muons, and the h boson decays into View the MathML sourcebb‾. The search is based on data from proton–proton collisions at a center-of-mass energy View the MathML sources=8 TeV collected with the CMS detector, corresponding to an integrated luminosity of 19.7 fb−119.7 fb−1. The h boson is assumed to be the standard model-like Higgs boson with a mass of 125 GeV. With no evidence for signal, upper limits are obtained on the product of the production cross section and the branching fraction of the A boson in the Zh channel. Results are also interpreted in the context of two Higgs doublet models.
