Abstract: (arXiv)

We report on a search for new particles in the diphoton channel using a data sample of

p\bar p

collisions at

\sqrt{s} = 1.96

TeV collected by the CDF II detector at the Fermilab Tevatron, with an integrated luminosity of 5.4 fb

^{-1}

. The diphoton invariant mass spectrum of the data agrees well with the standard model expectation. We set upper limits on the production cross section times branching ratio for the Randall-Sundrum graviton, as a function of diphoton mass. We subsequently derive lower limits on the graviton mass of 459 GeV

/c^{2}

and 963 GeV

/c^{2}

, at the 95% confidence level, for coupling parameters (

k/\bar{M}_{Pl}

) of 0.01 and 0.1 respectively.
