Cosmic e^\pm, \bar p, γand neutrino rays in leptocentric dark matter models
Xiao-Jun Bi, Xiao-Gang He, Ernest Ma +1
Dark matter annihilation is one of the leading explanations for the recently observed excesses in cosmic rays by PAMELA, ATIC, FERMI-LAT and HESS. Any dark matter annihilat…
Non-Thermal Production of WIMPs, Cosmic Excesses and -rays from the Galactic Center
Xiao-Jun Bi, Robert Brandenberger, Paolo Gondolo +3
In this paper we propose a dark matter model and study aspects of its phenomenology. Our model is based on a new dark matter sector with a U(1)' gauge symmetry plus a discrete symm…
Parameters in a Class of Leptophilic Dark Matter Models from PAMELA, ATIC and FERMI
Xiao-Jun Bi, Xiao-Gang He, Qiang Yuan
In this work we study a class of leptophilic dark matter models, where the dark matter interacts with the standard model particles via the gauge boson, to explain…
ATIC and PAMELA Results on Cosmic e^\pm Excesses and Neutrino Masses
Xiao-Jun Bi, Pei-Hong Gu, Tianjun Li +1
Recently the ATIC and PAMELA collaborations released their results which show the abundant e^\pm excess in cosmic rays well above the background, but not for the \bar{p}. Their dat…
