A bstractWe go a step further in the search for a consistent and realistic supergravity model of large-field inflation by building a class of models with the following features: during slow-roll, all the scalar fields other than the inflaton are frozen by large inflatondependent masses or removed from the spectrum; at the end of inflation, supersymmetry is spontaneously broken with naturally vanishing classical vacuum energy. We achieve this by combining some geometrical properties of the Kähler potential with the consistent use of a single nilpotent chiral superfield, in one-to-one correspondence with the supersymmetrybreaking direction in field space at the vacuum.

α-attractors: Planck, LHC and dark energy (2015, methodology): “In such case, with account of θ = 0 condition we can use the reconstruction method analogous to the one in [6], where it was applied to canonical shift symmetric Kähler potentials with Minkowski vacua.”
