DESCRIPTION:In this talk we present a model of inflation in which the infl
 aton field \nis a complex scalar field charged under a triplet of U(1) gau
 ge fields. We \ndecompose the perturbations into the adiabatic and entropy
  modes and calculate the curvature perturbation power spectrum and its cro
 ss-correlation to entropy modes. In addition to the metric tensor perturba
 tions\, there are tensor perturbations associated with the gauge field per
 turbations which are coupled to metric tensor perturbations. We show that 
 the correction in primordial gravitational tensor power spectrum induced f
 rom the matter tensor perturbation is a sensitive function of the gauge co
 upling.
