Symmetry constraints in inflation, [alpha]-vacua, and the three point function

Abstract The Ward identities for conformal symmetries in single field models of inflation are studied in more detail in momentum space. For a class of generalized single field models, where the inflaton action contains arbitrary powers of the scalar and its first derivative, we find that the Ward id...
