Query: Higgs at ILC in Universal Extra Dimensions in Light of Recent LHC Data   We present bounds on all the known universal extra dimension models from the
latest Higgs search data at the Large Hadron Collider, taking into account the
Kaluza-Klein (KK) loop effects on the dominant gluon-fusion production and on
the diphoton/digluon decay. The lower bound on the KK scale is from 500GeV to
1TeV depending on the model. We find that the Higgs production cross section
with subsequent diphoton decay can be enhanced by a factor 1.5 within this
experimental bound, with little dependence on the Higgs mass in between 115GeV
and 130GeV. We also show that in such a case the Higgs decay branching ratio
into a diphoton final state can be suppressed by a factor 80%, which is
marginally observable at a high energy/luminosity option at the International
Linear Collider. The Higgs production cross section at a photon-photon collider
can also be suppressed by a similar factor 90%, being well within the expected
experimental reach.
