Cosmological Perturbations in Palatini Formalism
Mio Kubota, Kin-ya Oda, Keigo Shimada +1
We investigate cosmological perturbations of scalar-tensor theories in Palatini formalism. First we introduce an action where the Ricci scalar is conformally coupled to a function…

Higgs inflation in metric and Palatini formalisms: Required suppression of higher dimensional operators
Ryusuke Jinno, Mio Kubota, Kin-ya Oda +1
We investigate the sensitivity of Higgs(-like) inflation to higher dimensional operators in the nonminimal couplings and in the potential, both in the metric and Palatini formalism…
