##### Abstract:
A search is presented for a standard model-like Higgs boson decaying to the μ$^{+}$μ$^{-}$ 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 μ$^{+}$μ$^{-}$ 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. ... mehr

##### Abstract (englisch):
A search is presented for a standard model-like Higgs boson decaying to the &#956;+&#956;- 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 &#956;+&#956;- 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 &#956;+&#956;-, 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. ... mehr
