Abstract
A bstract A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample corresponds to integrated luminosities up to 5.1 fb −1 at $ \sqrt{s}=7 $ TeV, and up to 5.3 fb −1 at $ \sqrt{s}=8 $ TeV . The results for five Higgs boson decay modes γγ , ZZ, WW, ττ , and bb, which show a combined local significance of 5 standard deviations near 125 GeV, are reviewed. A fit to the invariant mass of the two high resolution channels, γγ and ZZ → 4 ℓ , gives a mass estimate of 125 . 3 ± 0 . 4 (stat.) ± 0 . 5 (syst.) GeV. The measurements are interpreted in the context…
