Tevatron Signal for an Unmixed Radion
  The recent observation by the CDF Collaboration of an excess in $W$ plus dijet events, where the dijet invariant mass shows a 3.2$\sigma$ peak around $144 \pm 5$ GeV, is shown to be consistent with the production of a radion $\Phi$ of mass in this range, in association with a $W$ boson. It is shown that the $\Phi$, which is known to be similar to the Higgs boson in many aspects, differs from it in having a much larger cross-section for $q\bar q \to W\Phi$ and in decaying principally to gluons, rather than $b\bar b$ pairs. These appear to be the precise features demanded by the new particle interpretation of the CDF events. No modifications of the underlying model are required.
