A note on supergravity inflation in braneworld

Mudassar Sabir, Waqas Ahmed, Yungui Gong +3

We discuss supergravity inflation in braneworld cosmology for the class of potentials $V(\varphi )=\alpha {\varphi }^n\exp (-{\beta }^{\mathrm{m}}{\varphi }^{\mathrm{m}})$ with $m=1,2$. These minimal SUGRA models evade the $\eta$ problem…
