Effects of Radiative Corrections on Starobinsky Inflation
John Ellis, Tony Gherghetta, Kunio Kaneta +2
We analyze radiative corrections to the Starobinsky model of inflation arising from self-interactions of the inflaton, and from its Yukawa couplings, , to matter fermions, and d…

Effective interactions and on-shell recursion relation for massive spin 3/2
Tony Gherghetta, Wenqi Ke
We use on-shell methods to compute all three-point interactions of massive spin-3/2 particles involving a graviton and particles of spin . By employing the massive spinor-h…
