Constraints on a mixed model of dark matter particles and primordial black holes from the Galactic 511 keV line
Rong-Gen Cai, Yu-Chen Ding, Xing-Yu Yang +1
The galactic 511 keV gamma-ray line has been observed since 1970's, and was identified as the result of electron-positron annihilation, but the origin of such positrons is still no…
Direct detection of dark matter with resonant annihilation
Bo Li, Yu-Feng Zhou
In the scenario where the dark matter (DM) particles pair annihilate through a resonance particle , the constraint from DM relic density makes the corresponding cross s…
Strongly first order phase transition in the singlet fermionic dark matter model after LUX
Tai Li, Yu-Feng Zhou
We investigate an extension of the standard model (SM) with a singlet fermionic dark matter (DM) particle which interacts with the SM sector through a real singlet scalar. The pres…
Fourth generation Majorana neutrino, dark matter and Higgs physics
Shou-Shan Bao, Xue Gong, Zong-Guo Si +1
We consider extensions of the standard model with fourth generation fermions (SM4) in which extra symmetries are introduced such that the transitions between the fourth generation…
The 130 GeV gamma-ray line and Sommerfeld enhancements
Jing Chen, Yu-Feng Zhou
Recently, possible indications of line spectral features in the Fermi-LAT photon spectrum towards the galactic center have been reported. If the distinct line features arise from d…
Direct detection of fourth generation Majorana neutrino dark matter
Yu-Feng Zhou
Heavy stable fourth generation Majorana neutrinos contribute to a small fraction of the relic density of dark matter (DM) in the Universe. Due to its relatively strong coupling to…
Probing the fourth generation Majorana neutrino dark matter
Yu-Feng Zhou
Heavy fourth generation Majorana neutrino can be stable and contribute to a small fraction of the relic density of dark matter (DM) in the Universe. Due to its strong coupling to t…
