  In this paper, we study central production, in the inclusive case, to look
for graviton signals in large extra dimensional model using dilepton and
diphoton channels. We carefully analyze signal and possible Standard Model
background processes and study the feasibility of such new physics searches in
a relatively clean environment as in central production where the proton
fragments are mostly emitted in the forward direction, and there is a clear
rapidity gap between them and the centrally produced system. Our analysis shows
that the LHC with 14 TeV center of mass energy and 100 fb$^{-1}$ (300
fb$^{-1}$) of integrated luminosity can probe the effective gravity scale up to
3.6 TeV (4.4 TeV) in both the dilepton and diphoton channels.
