Cancellation of quantum corrections on the soft curvature perturbations
Yuichiro Tada, Takahiro Terada, Junsei Tokuda
We study the cancellation of quantum corrections on the superhorizon curvature perturbations from subhorizon physics beyond the single-clock inflation from the viewpoint of the cos…
Hybrid metric-Palatini Higgs inflation
Minxi He, Yusuke Mikura, Yuichiro Tada
We propose an extension of the Higgs inflation to the hybrid metric-Palatini gravity, where we introduce non-minimal couplings between Higgs and both the metric-type and the Palati…
Minimal -inflation in light of the conformal metric-affine geometry
Yusuke Mikura, Yuichiro Tada, Shuichiro Yokoyama
We motivate a minimal realization of slow-roll -inflation by incorporating the local conformal symmetry and the broken global symmetry in the metric-affine ge…
Revisiting non-Gaussianity in non-attractor inflation models in the light of the cosmological soft theorem
Teruaki Suyama, Yuichiro Tada, Masahide Yamaguchi
We revisit the squeezed-limit non-Gaussianity in the single-field non-attractor inflation models from the viewpoint of the cosmological soft theorem. In the single-field attractor…
Conformal inflation in the metric-affine geometry
Yusuke Mikura, Yuichiro Tada, Shuichiro Yokoyama
Systematic understanding for classes of inflationary models is investigated from the viewpoint of the local conformal symmetry and the slightly broken global symmetry in the framew…
