Matter Power Spectra in Viable Gravity Models with Massive Neutrinos
Chao-Qiang Geng, Chung-Chi Lee, Jia-Liang Shen
We investigate the matter power spectra in the power law and exponential types of viable theories along with massive neutrinos. The enhancement of the matter power spectrum…
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 $…
Revisiting Multi-Component Dark Matter with New AMS-02 Data
Chao-Qiang Geng, Da Huang, Chang Lai
We revisit the multi-component leptonically decaying dark matter (DM) scenario to explain the possible electron/positron excesses with the recently updated AMS-02 data. We find tha…
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.…
Kaluza-Klein theory for teleparallel gravity
Chao-Qiang Geng, Chang Lai, Ling-Wei Luo +1
We study teleparallel gravity in the \emph{original} Kaluza-Klein (KK) scenario. Our calculation of the KK reduction of teleparallel gravity indicates that the 5-dimensional torsio…
Correlation Between Muon and
Wei-Chi Chiu, Chao-Qiang Geng, Da Huang
While the muon anomaly can be successfully explained by some new physics models, most of them are severely constrained by the bound. This tension is more transpare…
