Query: Indirect constraints on the dark matter interpretation of excess
  positrons seen by AMS-02   Recently, an excess of high energy positrons in our Galaxy has been observed
by AMS-02. The spectrum obtained can be best fitted with the annihilation of
$\sim$ TeV dark matter particles. However, recent analysis of Dwarf galaxies by
Fermi/LAT observations highly constrains the TeV dark matter annihilation
cross-section, and rules out the $b\bar{b}$ and all the leptophilic channels
except $4-\mu$ channel. In this article, I show that the remaining possible
$4-\mu$ channel is also ruled out by using the observational data from
cool-core clusters. Therefore, all the leptophilic channels that can account
for the excess positrons seen in AMS-02, HEAT, and PAMELA are ruled out.
