The spatial distribution of dark-matter-annihilation originated gamma-ray line signal
Tong-Suo Lu, Tie-Kuang Dong, Jian Wu
The GeVTeV ray line signal is the smoking gun signature of the dark matter annihilation or decay. The detection of such a signal is one of the main targets of some space-bas…
Cosmogenic Nuclei Production Rate on the Lunar Surface
Tie-Kuang Dong, Su-Jun Yun, Tao Ma +5
A physical model of Geant4-based simulation of galactic cosmic ray (GCR) particles interaction with the lunar surface matter has been developed to investigate the production rate o…
Probe the 2 and 1 state level inversion with electron-nucleus scattering
Zai-jun Wang, Zhong-zhou Ren, Tie-kuang Dong
The neutron-rich even-even nuclei Mg, Si, S, and Ar are calculated with the RMF model and the phase-shift electron scattering method. Result…
AMS-02 positron excess: new bounds on dark matter models and hint for primary electron spectrum hardening
Lei Feng, Rui-Zhi Yang, Hao-Ning He +3
The data collected by ATIC, CREAM and PAMELA all display remarkable cosmic-ray-nuclei spectrum hardening above the magnetic rigidity 240 GV. One natural speculation is that…
