A bound on universal extra dimension models from up to 2 fb−1 of LHC data at 7 TeV

The recent up to ∼2 fb−1 of data from the ATLAS and CMS experiments at the CERN Large Hadron Collider at 7 TeV put an upper bound on the production cross section of a Higgs-like particle. We translate the results of the H→WW→lνlν and H→γγ as well as the combined analysis by the ATLAS and CMS into an allowed region for the Kaluza-Klein (KK) mass MKK and the Higgs mass MH 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.
