dc.description.abstract | A search is presented for a standard model-like Higgs boson decaying to the ?+?? or e+e? final states based on proton–proton collisions recorded by the CMS experiment at the CERN LHC. The data correspond to integrated luminosities of 5.0 fb?1 at a centre-of-mass energy of 7 TeV and 19.7 fb?1 at 8 TeV for the ?+?? search, and of 19.7 fb?1 at 8 TeV for the e+e? search. Upper limits on the production cross section times branching fraction at the 95% confidence level are reported for Higgs boson masses in the range from 120 to 150 GeV. For a Higgs boson with a mass of 125 GeV decaying to ?+??, the observed (expected) upper limit on the production rate is found to be 7.4 (6.5?1.9 +2.8) times the standard model value. This corresponds to an upper limit on the branching fraction of 0.0016. Similarly, for e+e?, an upper limit of 0.0019 is placed on the branching fraction, which is ?3.7×105 times the standard model value. These results, together with recent evidence of the 125 GeV boson coupling to ?-leptons with a larger branching fraction consistent with the standard model, confirm that the leptonic couplings of the new boson are not flavour-universal | en_US |
