Query: 3-form inflation in Randall-Sundrum II   It has been shown in the last few years that 3-form fields present viable
cosmological solutions for inflation and dark energy with particular observable
signatures distinct from those of canonical single scalar field inflation. The
aim of this work is to explore the dynamics of a single 3-form in five
dimensional Randall-Sundrum II braneworld scenario, in which a 3-form is
confined to the brane and only gravity propagates in the bulk. We compare the
solutions with the standard four dimensional case already studied in the
literature. In particular, we evaluate how the spectral index and the ratio of
tensor to scalar perturbations are influenced by the presence of the bulk and
put constraints on the parameters of the models in the light of the recent
Planck 2015 data.
