Inflation in f(R,ϕ) Gravity with Exponential Model
We are taking action of f(R) gravity with a nonminimal coupling to a massive inflaton field. A f(R,ϕ) model is chosen which leads to the scalar-tensor theory which can be transformed to Einstein frame by conformal transformation. To avoid the vagueness of the frame dependence, we evaluate the exact...
