We present bounds on all the known universal extra dimension models from thelatest Higgs search data at the Large Hadron Collider, taking into account theKaluza-Klein (KK) loop effects on the dominant gluon-fusion production and onthe diphoton/digluon decay. The lower bound on the KK scale is from 500GeV to1TeV depending on the model. We find that the Higgs production cross sectionwith subsequent diphoton decay can be enhanced by a factor 1.5 within thisexperimental bound, with little dependence on the Higgs mass in between 115GeVand 130GeV. We also show that in such a case the Higgs decay branching ratiointo a diphoton final state can be suppressed by a factor 80%, which ismarginally observable at a high energy/luminosity option at the InternationalLinear Collider. The Higgs production cross section at a photon-photon collidercan also be suppressed by a similar factor 90%, being well within the expectedexperimental reach.
