Volkov–Akulov–Starobinsky supergravity revisited
Abstract We find new realizations of Volkov–Akulov–Starobinsky supergravity, i.e. Starobinsky inflationary models in supergravity coupled to a nilpotent superfield describing Volkov–Akulov goldstino. Our constructions are based on the no-scale Kähler potential $$K=-3\log (T+\overline{T})$$ K=-3log(T...
