Search for a pseudoscalar boson decaying into a Z boson and the 125 GeV Higgs boson in llbb final states
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-...

| description | 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 recently discovered 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. |

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 recently discovered 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.</abstract><pub>Elsevier</pub><doi>10.1016/j.physletb.2015.07.010</doi><tpages>23</tpages><orcidid>https://orcid.org/0000-0003-0885-824X</orcidid><orcidid>https://orcid.org/0000-0001-7476-0158</orcidid><orcidid>https://orcid.org/0000-0001-6027-4511</orcidid><orcidid>https://orcid.org/0000-0002-2939-5646</orcidid><orcidid>https://orcid.org/0000-0002-5230-8387</orcidid><orcidid>https://orcid.org/0000-0003-3154-3123</orcidid><orcidid>https://orcid.org/0000-0002-5524-880X</orcidid><orcidid>https://orcid.org/0000-0001-6185-2045</orcidid><orcidid>https://orcid.org/0000-0001-9580-683X</orcidid><orcidid>https://orcid.org/0000-0002-1275-7292</orcidid><orcidid>https://orcid.org/0000-0003-3090-2948</orcidid><orcidid>https://orcid.org/0000-0002-1935-623X</orcidid></addata></record> |
