Realising mutated hilltop inflation in supergravity
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
We present N=1 supergravity models of mutated hilltop inflation (MHI) for both large and small field sectors. Models with canonical kinetic terms are developed based on a shift symmetric Kähler potential in inflaton superfield, and with a superpotential linear in Goldstino superfield. We also construct models with non-canonical kinetic terms for MHI by generalising the shift symmetry. We found that a good fraction of the models can address the entire branch of MHI in a single framework.
