  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 b anti-b.
The search is based on data from proton-proton collisions at a center-of-mass
energy sqrt(s)=8 TeV collected with the CMS detector, corresponding to an
integrated luminosity of 19.7 inverse femtobarns. 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.
