Query: Multilepton signatures for scalar dark matter searches in coannihilation
  scenario   We revisit the scalar singlet dark matter (DM) scenario with a pair of dark
lepton partners which form a vectorlike Dirac fermionic doublet. The extra
doublet couples with the Standard Model (SM) leptonic doublet and the scalar
singlet via a non-SM-like Yukawa structure. As a result, (i) since the extra
fermionic states interact with other dark sector particles as well as the SM
via gauge and Yukawa interactions, it gives rise to new DM annihilation
processes including pair annihilation as well as coannihilation channels, and
(ii) such a Yukawa structure opens up new production channels for leptonic
final states giving much enhancement in cross sections to search for dark
matter in the LHC. Using suitable kinematic observables, we train a {\em
boosted decision tree} (BDT) classifier to separate enhanced but still feeble
light leptonic signals from the background in an effective manner. On the other
hand, the same technique is applied to study $\tau$-tagged jets in the search
for DM signals.
