High Scale Validity of the DFSZ Axion Model with Precision
Satsuki Oda, Yutaro Shoji, Dai-suke Takahashi
With the assumption of classical scale invariance at the Planck scale, the DFSZ axion model can generate the Higgs mass terms of the appropriate size through technically natural pa…
Maximum value of the spin-independent cross section in the THDM+a
Tomohiro Abe, Motoko Fujiwara, Junji Hisano +1
We investigate the maximum value of the spin-independent cross section () in a dark matter (DM) model called the two-Higgs doublet model + a (THDM+a). This model can e…
To be, or not to be finite? The Higgs potential in Gauge-Higgs Unification
Junji Hisano, Yutaro Shoji, Atsuyuki Yamada
In this paper, we investigate the finiteness of the Higgs effective potential in an Gauge-Higgs Unification (GHU) model defined on . We…
Bounce Configuration from Gradient Flow
So Chigusa, Takeo Moroi, Yutaro Shoji
Based on the gradient flow, we propose a new method to determine the bounce configuration for false vacuum decay. Our method is applicable to a large class of models with multiple…
Fast-Rolling Relaxion
Masahiro Ibe, Yutaro Shoji, Motoo Suzuki
We discuss new mechanisms to stop the relaxion field during inflation. They can be realized in a generic model, including the original model but in a quite different parameter regi…
