1. A model with flavor-dependent gauged symmetrySupported by National Center for Theoretical Sciences and MoST (MoST-104-2112-M-007-003-MY3 and MoST-107-2119-M-007-013-MY3) / Mu, Linping ; Okada, Hiroshi ; Geng, Chao-Qiang
We propose a new model with flavor-dependent gauged symmetry in addition to the flavor-blind symmetry in the Standard Model. [...]

3. Large ν ‐ ν ¯ $$ \nu \hbox{-} \overline{\nu} $$ oscillations from high-dimensional lepton number violating operator / Geng, Chao-Qiang ; Huang, Da
It is usually believed that the observation of the neutrino-antineutrino ( ν ‐ ν ¯ $$ \nu \hbox{-} \overline{\nu} $$ ) oscillations is almost impossible since the oscillation probabilities are expected to be greatly suppressed by the square of tiny ratio of neutrino masses to energies. [...]

4. Probing gravitational non-minimal coupling with dark energy surveys / Geng, Chao-Qiang ; Lee, Chung-Chi ; Wu, Yi-Peng
We investigate observational constraints on a specific one-parameter extension to the minimal quintessence model, where the quintessence field acquires a quadratic coupling to the scalar curvature through a coupling constant ξ . [...]

6. Direct detection of exothermic dark matter with light mediator / Geng, Chao-Qiang ; Huang, Da ; Lee, Chun-Hao ; Wang, Qing
We study the dark matter (DM) direct detection for the models with the effects of the isospin-violating couplings, exothermic scatterings, and/or the lightness of the mediator, proposed to relax the tension between the CDMS-Si signals and null experiments. [...]

9. CP violations in predictive neutrino mass structures / Geng, Chao-Qiang ; Huang, Da ; Tsai, Lu-Hsing
We study the CP-violation effects from two types of neutrino mass matrices with (i) (Mν)ee=0 , and (ii) (Mν)ee=(Mν)eμ=0 , which can be realized by the high-dimensional lepton number violating operators ℓ¯RcγμLL(DμΦ)Φ2 and ℓ¯RclR(DμΦ)2Φ2 , respectively. [...]

10. Connecting neutrino masses and dark matter by high-dimensional lepton number violation operator / Geng, Chao-Qiang ; Huang, Da ; Tsai, Lu-Hsing ; Wang, Qing
We propose a new model with the Majorana neutrino masses generated at two-loop level, in which the lepton number violation (LNV) processes, such as neutrino-less double beta decays, are mainly induced by the dimension-7 LNV effective operator O 7 = l ¯ R c γ μ L L D μ Φ Φ Φ $$ {\mathcal{O}}_7={\overline{l}}_R^c{\gamma}^{\mu }{L}_L\left({D}_{\mu}\varPhi \right)\varPhi \varPhi $$ .
