英文摘要A self-consistent global fitting method based on the Markov Chain Monte Carlo technique to study the dark matter (DM) property associated with the cosmic ray electron/positron excesses was developed in our previous work. In this work we further improve the previous study to include the hadronic branching ratio of DM annihilation/decay. The PAMELA (p) over bar /p data are employed to constrain the hadronic branching ratio. We find that the 95% (2 sigma) upper limits of the quark branching ratio allowed by the PAMELA (p) over bar /p data is similar to 0.032 for DM annihilation and similar to 0.044 for DM decay, respectively. This result shows that the DM coupling to pure leptons is indeed favored by the current data. Based on the global fitting results, we further study the neutrino emission from DM in the galactic center. Our predicted neutrino flux is some smaller than previous works since the constraint from gamma-rays is involved. However, it is still capable to be detected by the forthcoming neutrino detector such as IceCube. The improved points of the present study compared with previous works include: (1) the DM parameters, both the particle physical ones and astrophysical ones, are derived in a global fitting way, (2) constraints from various species of data sets, including gamma-rays and antiprotons are included, and (3) the expectation of neutrino emission is fully self-consistent.
