Statistics of coarse-grained cosmological fields in stochastic inflation
Yuichiro Tada, Vincent Vennin
We present a generic framework to compute the one-point statistics of cosmological perturbations, when coarse-grained at an arbitrary scale , in the presence of quantum diffusio…
Primordial black holes in peak theory with a non-Gaussian tail
Naoya Kitajima, Yuichiro Tada, Shuichiro Yokoyama +1
In this paper, we update the peak theory for the estimation of the primordial black hole (PBH) abundance, particularly by implementing the critical behavior in the estimation of th…
On UV-completion of Palatini-Higgs inflation
Yusuke Mikura, Yuichiro Tada
We investigate the UV-completion of the Higgs inflation in the metric and the Palatini formalisms. It is known that the cutoff scales for the perturbative unitarity of these inflat…
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…
