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 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.

Light scalars within the $\mathcal{CP}$-conserving Aligned-two-Higgs-doublet model
All seven light-scalar scenarios of the CP-conserving aligned two-Higgs-doublet model contain sizeable parameter regions compatible with current collider and flavour data, with the lightest new scalars bounded by LEP and LHC searches.
