CP Violation in Predictive Neutrino Mass Structures
Chao-Qiang Geng, Da Huang, Lu-Hsing Tsai
We study the CP violation effects from two types of neutrino mass matrices with (i) , and (ii) , which can be realized by the high dimensiona…
Connecting Neutrino Masses and Dark Matter by High-dimensional Lepton Number Violation Operator
Chao-Qiang Geng, Da Huang, Lu-Hsing Tsai +1
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 neutrinoless double beta decays,…
Comment on "A three-loop radiative neutrino mass model with dark matter" [Phys. Lett. B 741 (2015) 163]
Chao-Qiang Geng, Da Huang, Lu-Hsing Tsai
We revisit the calculation of the three-loop diagrams for the radiative neutrino mass generation and consider some relevant constraints on the model recently proposed by L. Jin {\i…
Study of Two-Loop Neutrino Mass Generation Models
Chao-Qiang Geng, Lu-Hsing Tsai
We study the models with the Majorana neutrino masses generated radiatively by two-loop diagrams due to the Yukawa and effective co…
Constraints on the septet-doublet mixing models from oblique parameters
Chao-Qiang Geng, Lu-Hsing Tsai, Yao Yu
The limitations of the doublet-septet mixing models by the deviations of electroweak oblique parameters and are studied. In the minimal model, the mixture of the septet $…
Loop-induced Neutrino Masses: A Case Study
Chao-Qiang Geng, Da Huang, Lu-Hsing Tsai
We study the cocktail model in which the Majorana neutrino masses are generated by the so-called "cocktail" three-loop diagrams with the dark matter particle running in the loops.…
