Query: Combination of e+/e- ratio from AMS-02 and gamma ray line from Fermi-LAT
  with implication for Dark Matter   The precise AMS-02 data provide definite information for the e+/e- ratio in
100 - 350 GeV region. Assuming that the recent gamma ray line observed by
Fermi-LAT experiment is product of dark matter in space and taken as input. We
make a global fit for the AMS-02 e+/e- spectrum with both dark matter and
pulsar contribution. For this spectrum over 130 GeV, pulsar is the dominant
contribution. We also investigate the constrains on hadron production from dark
matter annihilation.
