Abstract
A new hybrid inflationary scenario in the context of f(R,□R)-gravity is proposed.Demanding the waterfall field to `support the potential from below' [unlike the original proposal by Stewart in Phys. Lett. B 345, 414 (1995)],we demonstrate that the scalar potential is similar to that of the large-field chaotic inflation model proposed by Linde in Phys. Lett. B 129, 177 (1983).Inflationary observables are used to constrain the parameter space of our model;in the process, an interesting limit on the number of e-folds N is found.
