Anisotropic bispectrum of curvature perturbations from primordial non-Abelian vector fields

We consider a primordial SU(2) vector multiplet during inflation in models where quantum fluctuations of vector fields are involved in producing the curvature perturbation. Recently, a lot of attention has been paid to models populated by vector fields, given the interesting possibility of generatin...
