A bound on Universal Extra Dimension Models from up to 2fb^{-1} of LHC Data at 7TeV
arXiv:1108.1764 · doi:10.1016/j.physletb.2011.12.061
Abstract
The recent up to 2fb^{-1} of data from the ATLAS and CMS experiments at the CERN Large Hadron Collider at 7TeV put an upper bound on the production cross section of a Higgs-like particle. We translate the results of the H -> WW -> l nu l nu and H -> gamma gamma as well as the combined analysis by the ATLAS and CMS into an allowed region for the Kaluza-Klein (KK) mass M_{KK} and the Higgs mass for all the known Universal Extra Dimension (UED) models in five and six dimensions. Our bound is insensitive to the detailed KK mass splitting and mixing and hence complementary to all other known signatures.
arXiv comment(v2) accepted for publication in Phys. Lett. B, newer data shown in Lepton-Photon conference (especially from separate WW and di-photon channels) are included, title changed accordingly, comments and references added; (v1) 10 pages, 2 figures, 2 tables
