Formulating E- & T-Model Inflation in Supergravity

Abstract We present novel realizations of E- and T-model inflation within Supergravity which are largely associated with the existence a pole order one two respectively in kinetic term inflaton superfield. This arises due to selected logarithmic Kahler potentials K , parameterize hyperbolic manifolds scalar curvature related coefficient (− N ) < 0 term. The superpotential W exhibits same R charge inflaton-accompanying superfield includes all allowed terms. role can be played by gauge singlet or non-singlet Models for inflaton, require = 2, some tuning – 10 −5 between terms predict tensor-to-scalar ratio r at level 0.001. totally eluded more structured ’s, values increasing spectral index close even equal its central observational value.
