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…
Non-minimal quartic inflation in classically conformal U(1) extended Standard Model
Satsuki Oda, Nobuchika Okada, Digesh Raut +1
We propose quartic inflation with non-minimal gravitational coupling in the context of the classically conformal U(1)_X extension of the SM. In this model, the U(1)_X gauge symmetr…
Right-handed neutrino dark matter in the classically conformal U(1)' extended Standard Model
Satsuki Oda, Nobuchika Okada, Dai-suke Takahashi
We consider the dark matter (DM) scenario in the context of the classically conformal U(1)' extended standard model (SM), with three right-handed neutrinos (RHNs) and the U(1)' Hig…
Classically conformal U(1)' extended standard model, electroweak vacuum stability, and LHC Run-2 bounds
Arindam Das, Satsuki Oda, Nobuchika Okada +1
We consider the minimal U(1)' extension of the standard model (SM) with the classically conformal invariance, where an anomaly-free U(1)' gauge symmetry is introduced along with th…
Classically conformal U(1) extended Standard Model and Higgs vacuum stability
Satsuki Oda, Nobuchika Okada, Dai-suke Takahashi
We consider the minimal U(1) extension of the Standard Model (SM) with conformal invariance at the classical level, where in addition to the SM particle contents, three ge…
