N2 - We suppose that a vector field perturbation causes part of the primordial curvature perturbation. The non-Gaussianity parameter f_NL is then, in general, statistically anisotropic. We calculate its form and magnitude in the curvaton scenario and in the end-of-inflation scenario. We show that this anisotropy could easily be observable.

AB - We suppose that a vector field perturbation causes part of the primordial curvature perturbation. The non-Gaussianity parameter f_NL is then, in general, statistically anisotropic. We calculate its form and magnitude in the curvaton scenario and in the end-of-inflation scenario. We show that this anisotropy could easily be observable.
