Abstract
We report on a search for new particles in the diphoton channel using a data sample of pp̄ collisions at √s=1.96TeV collected by the CDF II detector at the Fermilab Tevatron, with an integrated luminosity of 5.4fb⊃-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 459GeV/c2 and 963GeV/c2, at the 95% confidence level, for coupling parameters (k/M̄Pl) of 0.01 and 0.1, respectively. © 2011 American Physical Society.
