1. Radiative production of nonthermal dark matter / Kaneta, Kunio ; Mambrini, Yann ; Olive, Keith A.
We compare dark matter production from the thermal bath in the early universe with its direct production through the decay of the inflaton. [...]

2. 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. [...]

3. New weak-scale physics from SO(10) with high-scale supersymmetry / Ellis, Sebastian A. R. ; Gherghetta, Tony ; Kaneta, Kunio ; Olive, Keith A.
Gauge coupling unification and the stability of the Higgs vacuum are among two of the cherished features of low-energy supersymmetric models. [...]

4. Gravitino decay in high scale supersymmetry with R-parity violation / Dudas, Emilian ; Gherghetta, Tony ; Kaneta, Kunio ; Mambrini, Yann ; et al
We consider the effects of R-parity violation due to the inclusion of a bilinear μLHu superpotential term in high-scale supersymmetric models with an EeV scale gravitino as dark matter. [...]

5. Self-interacting dark matter and muon ( g − 2) in a gauged U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ model / Kamada, Ayuki ; Kaneta, Kunio ; Yanagi, Keisuke ; Yu, Hai-Bo
We construct a self-interacting dark matter model that could simultaneously explain the observed muon anomalous magnetic moment. [...]

6. Sterile neutrino dark matter from right-handed neutrino oscillations / Kadota, Kenji ; Kaneta, Kunio
We study a scenario where sterile neutrino (either warm or cold) dark matter (DM) is produced through (nonresonant) oscillations among right-handed neutrinos (RHNs) and can constitute the whole DM in the Universe, in contrast to the conventional sterile neutrino production through its mixing with the left-handed neutrinos. [...]

7. Very low scale Coleman-Weinberg inflation with nonminimal coupling / Kaneta, Kunio ; Seto, Osamu ; Takahashi, Ryo
We study viable small-field Coleman-Weinberg (CW) inflation models with the help of nonminimal coupling to gravity. [...]

8. 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. [...]

10. Thermal relic dark matter beyond the unitarity limit / Harigaya, Keisuke ; Ibe, Masahiro ; Kaneta, Kunio ; Nakano, Wakutaka ; et al
We discuss a simple model of thermal relic dark matter whose mass can be much larger than the so-called unitarity limit on the mass of point-like particle dark matter. [...]
