Q-balls in Non-Minimally Coupled Palatini Inflation and their Implications for Cosmology

A. K. Lloyd-Stubbs, J. McDonald

We demonstrate the existence of Q-balls in non-minimally coupled inflation models with a complex inflaton in the Palatini formulation of gravity. We show that there exist Q-ball so…
