Constraints on Dark Matter Annihilation Cross Section in Scenarios of Brane-World and Quintessence
Wan-Lei Guo, Xin Zhang
We investigate the dark matter annihilation in the brane-world and quintessence scenarios, in which the modified cosmological expansion rate can enhance the thermal relic density o…
Enhancement of Dark Matter Annihilation via Breit-Wigner Resonance
Wan-Lei Guo, Yue-Liang Wu
The Breit-Wigner enhancement of the thermally averaged annihilation cross section <σv> is shown to provide a large boost factor when the dark matter annihilation process nears a na…
Gauge-singlet dark matter in a left-right symmetric model with spontaneous CP violation
Wan-Lei Guo, Li-Ming Wang, Yue-Liang Wu +2
We propose a dark matter (DM) scenario in an extension of a left-right symmetric model with a gauge-singlet scalar field. The gauge-singlet scalar can automatically become a DM can…
The Dark Matter Constraints on the Left-Right Symmetric Model with Z_2 Symmetry
Wan-lei Guo, Li-ming Wang, Yue-liang Wu +1
In the framework of Left-Right symmetric model, we investigate an interesting scenario, in which the so-called VEV seesaw problem can be naturally solved with Z_2 symmetry. In such…
Sterile Neutrinos as the Warm Dark Matter in the Type II Seesaw Model
Wan-lei Guo
In the framework of type II seesaw mechanism we discuss the number of sterile right-handed Majorana neutrinos being the warm dark matter (WDM). When the type II seesaw mass term $M…
Neutrino Masses, Lepton Flavor Mixing and Leptogenesis in the Minimal Seesaw Model
Wan-lei Guo, Zhi-zhong Xing, Shun Zhou
We present a review of neutrino phenomenology in the minimal seesaw model (MSM), an economical and intriguing extension of the Standard Model with only two heavy right-handed Major…
