Higgs Boson Searches at CMS and ATLAS
Searches for Higgs bosons decaying to a variety of final states have been performed with the CMS and ATLAS detectors in 35-38 pb$^{-1}$ of proton-proton collisions at the LHC. No evidence of a Higgs boson is found, and limits are set on the production rates as functions of mass and, for some channel...

description | Searches for Higgs bosons decaying to a variety of final states have been performed with the CMS and ATLAS detectors in 35-38 pb$^{-1}$ of proton-proton collisions at the LHC. No evidence of a Higgs boson is found, and limits are set on the production rates as functions of mass and, for some channels, other model parameters. The strongest constraints come from the $H\rightarrow WW\rightarrow\ell\nu\ell\nu$ channel, where both ATLAS and CMS independently exclude Higgs boson production with a rate of 2.1 times the Standard Model prediction for a Higgs boson with $m_{H}=160$~GeV. Projections of the expected sensitivity with higher luminosity show that both experiments expect to exclude a Standard Model Higgs boson in the mass range $130<m_{H}<460$~GeV with 1 fb$^{-1}$ of integrated luminosity. |
