Exclusive decay of P-wave Bottomonium into double J/ψ
Juan Zhang, Hairong Dong, Feng Feng
We calculate the order-v^2 relativistic correction of J/ψ, including electromagnetic correction, to χ_{bJ}-> J/ψJ/ψ, in the framework of NRQCD factorization formula. The relativist…
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…
Galactic diffuse gamma rays --- recalculation based on the new measurements of cosmic electron spectrum
Juan Zhang, Qiang Yuan, Xiao-Jun Bi
In this work, we revisit the all-sky Galactic diffuse -ray emission taking into account the new measurements of cosmic ray electron/positron spectrum by PAMELA, ATIC and Fermi,…
Clumpiness enhancement of charged cosmic rays from dark matter annihilation with Sommerfeld effect
Qiang Yuan, Xiao-Jun Bi, Jia Liu +3
Boost factors of dark matter annihilation into antiprotons and electrons/positrons due to the clumpiness of dark matter distribution are studied in detail in this work, taking the…
Discriminating different scenarios to account for the cosmic excess by synchrotron and inverse Compton radiation
Juan Zhang, Xiao-jun Bi, Jia Liu +4
The excesses of the cosmic positron fraction recently measured by PAMELA and the electron spectra by ATIC, PPB-BETS, Fermi and H.E.S.S. indicate the existence of primary electron a…
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…
