1. Hillclimbing inflation in metric and Palatini formulations / Jinno, Ryusuke ; Kaneta, Kunio ; Oda, Kin-ya ; Park, Seong Chan
A new setup of cosmic inflation with a periodic inflaton potential and conformal factor is discussed in the metric and Palatini formulations of gravity. [...]

2. Particle decay in Gaussian wave-packet formalism revisited / Ishikawa, Kenzo ; Oda, Kin-ya
We derive Fermi’s golden rule in the Gaussian wave-packet formalism of quantum field theory, proposed by Ishikawa, Shimomura, and Tobita, for particle decay within a finite time interval. [...]

3. Hill-climbing Higgs inflation / Jinno, Ryusuke ; Kaneta, Kunio ; Oda, Kin-ya
We propose a realization of cosmic inflation with the Higgs field when the Higgs potential has degenerate vacua by employing the recently proposed idea of hill-climbing inflation. [...]

4. Di-Higgs enhancement by neutral scalar as probe of new colored sector / Nakamura, Koji ; Nishiwaki, Kenji ; Oda, Kin-ya ; Park, Seong Chan ; et al
We study a class of models in which the Higgs pair production is enhanced at hadron colliders by an extra neutral scalar. [...]

5. Predictions on mass of Higgs portal scalar dark matter from Higgs inflation and flat potential / Yuta Hamada ; Hikaru Kawai ; Kin-ya Oda
We consider the Higgs portal Z 2 scalar model as the minimal extension of the Standard Model (SM) to incorporate the dark matter. [...]

6. Minimal Higgs inflation / Hamada, Yuta ; Kawai, Hikaru ; Oda, Kin-ya
We consider a possibility that the Higgs field in the Standard Model (SM) serves as an inflaton when its value is around the Planck scale. [...]
