Violating Electrodynamics and Chern-Simons Modified Gravity
Mingzhe Li, Yi-Fu Cai, Xiulian Wang +1
The electrodynamics with a Chern-Simons term violates Lorentz and symmetries with a non-vanishing . For a fixed vector , in this paper we…
Visible and Dark Matter Genesis and Cosmic Positron/Electron Excesses
Pei-Hong Gu, Utpal Sarkar, Xinmin Zhang
Dark and baryonic matter contribute comparable energy density to the present Universe. The dark matter may also be responsible for the cosmic positron/electron excesses. We connect…
Double Type-II Seesaw, Baryon Asymmetry and Dark Matter for Cosmic e^\pm Excesses
Pei-Hong Gu, Hong-Jian He, Utpal Sarkar +1
We construct a new realization of type-II seesaw for neutrino masses and baryon asymmetry by extending the standard model with one light and two heavy singlet scalars besides one H…
Cosmic Ray Positrons from Cosmic Strings
Robert Brandenberger, Yi-Fu Cai, Wei Xue +1
We study the spectrum of cosmic ray positrons produced by a scaling distribution of non-superconducting cosmic strings. In this scenario, the positrons are produced from the jets w…
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…
PAMELA data and leptonically decaying dark matter
Peng-fei Yin, Qiang Yuan, Jia Liu +4
Recently PAMELA released their first results on the positron and antiproton ratios. Stimulated by the new data, we studied the cosmic ray propagation models and calculated the seco…
