Query: Constraints on box-shaped cosmic ray electron feature from dark matter
  annihilation with the AMS-02 and DAMPE data   Precise measurements of spectra of cosmic ray electrons and positrons can
effectively probe the nature of dark matter (DM) particles. In a class of
models where DM particles initially annihilate into a pair of intermediate
particles which then decay into standard model particles, box-shaped spectra
can be generated. Such a kind of spectra are distinct from astrophysical
backgrounds, and can probably be regarded as characteristic features of the DM
annihilation. In this work, we search for such a feature in the total electron
plus positron spectrum measured by AMS-02 and DAMPE. No significant evidence
for such a DM annihilation component has been found. The 95\% confidence level
upper limits of the velocity-weighted annihilation cross section are derived,
which range from $\sim 10^{-26}~{\rm cm^3~s^{-1}}$ for DM mass of 50 GeV to
$\sim 10^{-23}~{\rm cm^3~s^{-1}}$ for DM mass of 10 TeV.
