A bound on Universal Extra Dimension Models from up to 2fb^{-1} of LHC Data at 7TeV

Understand

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 $M_H$ 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.
