The 750 GeV diphoton resonance as a singlet scalar in an extra dimensional model
Chengfeng Cai, Zhao-Huan Yu, Hong-Hao Zhang
We interpret the 750~GeV diphoton excess recently found in the 13~TeV LHC data as a singlet scalar in an extra dimensional model, where one extra dimension is introduced. In the mo…
Perturbativity Limits for Scalar Minimal Dark Matter with Yukawa Interactions: Septuplet
Chengfeng Cai, Ze-Min Huang, Zhaofeng Kang +2
The candidate of minimal dark matter (MDM) is limited if one demands perturbativity up to a very high scale, and it was believed that the MDM model with a real scalar septuplet cou…
Confronting the real scalar septuplet minimal dark matter model with vacuum stability, perturbativity, and Type-I and Type-III seesaws
Chengfeng Cai, Ze-Min Huang, Zhaofeng Kang +2
We study a real scalar septuplet model which has a neutral component regarded as a dark matter particle candidate. The calculation of its thermal relic abundance without (with) the…
Majorana neutrinos with point interactions
Chengfeng Cai, Hong-Hao Zhang
We propose a realistic model with Majorana neutrinos in the framework of unifying the three generations of fermions by point interactions in an extra dimension. This model can simu…
