  In the models with large extra-dimensions, we examine the production of a
vector boson (\gamma / Z) in association with the Kaluza-Klein (KK) modes of
the graviton via gluon fusion. At the leading order, the process takes place
through quark-loop box and triangle diagrams and it is ultraviolate finite. We
report the results for the LHC. We also discuss the issues of anomaly and
decoupling of heavy quarks in the amplitude.
