Anisotropic inflation in BransâDicke gravity

We study anisotropic inflation in the BransâDicke gravity in the presence of an abelian gauge field where the gauge field is non-minimally coupled to the inflaton. We show that the degree of anisotropy, under slow-roll approximations, is proportional to slow-roll parameter of the theory. As a demons...
