Baryon number non-conservation as Peccei-Quinn mechanism
Takahiro Ohata, Kengo Takeuchi, Koji Tsumura
Baryon number is an accidental symmetry in the standard model, while Peccei-Quinn symmetry is hypothetical symmetry which is introduced to solve the strong CP problem. We study the…
A study on energy resolution of CANDLES detector
B. T. Khai, S. Ajimura, W. M. Chan +20
In a neutrinoless double-beta decay () experiment, energy resolution is important to distinguish between and background events. CAlcium fluoride for studies of Neutrin…
Low background measurement in CANDLES-III for studying the neutrino-less double beta decay of Ca
S. Ajimura, W. M. Chan, K. Ichimura +65
We developed a CANDLES-III system to study the neutrino-less double beta (0) decay of Ca. The proposed system employs 96 CaF scintillation crystals (305 kg) with…
TeV-scale Majorogenesis
Yoshihiko Abe, Yu Hamada, Takahiro Ohata +2
The Majoron, the Nambu-Goldstone boson of lepton number symmetry, is an interesting candidate for dark matter as it deeply connects the dark matter and neutrino physics. In this pa…
The energy calibration system for CANDLES using (n, γ) reaction
T. Iida, K. Mizukoshi, T. Ohata +28
CAlcium fluoride for the study of Neutrinos and Dark matters by Low-energy Spectrometer (CANDLES) searches for neutrino-less double beta decay of Ca using a CaF scintill…
Charged scalars confronting neutrino mass and muon g-2 anomaly
Nabarun Chakrabarty, Cheng-Wei Chiang, Takahiro Ohata +1
The present work introduces two possible extensions of the Standard Model Higgs sector. In the first case, the Zee-Babu type model for the generation of neutrino mass is augmented…
Ma-xion: Majoron as QCD axion in a radiative seesaw model
Ernest Ma, Takahiro Ohata, Koji Tsumura
The smallness of neutrino mass, the strong CP problem, and the existence of dark matter are explained in an economical way. The neutrino mass is generated by the colored version of…
