英文摘要Dark matter annihilation is one of the leading explanations for recent cosmic e(+/-) excess observations by PAMELA, ATIC, FERMI-LAT, and H. E. S. S. Any dark matter annihilation model proposed to explain these data has to comply with the fact that PAMELA data show excesses only in e(+/-) spectrum but not in antiprotons. It is interesting to ask whether the annihilation mode into antiprotons is completely disallowed or just suppressed at low energies. Most proposed models have negligible antiprotons in all energy ranges. In this work we investigate the leptocentric U(1)(B-3Li) dark matter model, and show that this model can explain the e(+/-) excesses with suppressed antiproton mode at low energies. But at higher energies there are sizable antiproton excesses. Near future data from PAMELA and AMS02 can provide crucial tests for this type of model. Cosmic gamma ray data can further rule out some of the models. We also show that this model has interesting neutrino signatures.
