Pole inflation in Jordan frame supergravity

I will talk about inflation models in Jordan frame supergravity based on our paper arXiv:1709.03440. Assuming that an inflaton has the canonical kinetic term in Jordan frame where an inflaton non-minimally couples to the spacetime curvature, I will construct inflation models which are compatible with observational result of spectral index, tensor to scalar ratio and amplitude of curvature perturbation through pole inflation technique. Then I will discuss their relation to the models based on Einstein frame supergravity.
