The search is based on data from proton–proton collisions at a center-of-mass energy s=8 TeV collected with the CMS detector, corresponding to an integrated luminosity of 19.7 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. © 2015 CERN for the benefit of the CMS Collaborationeninfo:eu-repo/semantics/openAccess2HDMBSMCMSHiggsMSSMArticle7482212432-s2.0-8504083144910.1016/j.physletb.2015.07.010Q1
