abstract
Motivated by recent cosmic ray experimental results there has been a proposition for a scenario where a secluded dark matter particle annihilates, primarily, into Standard Model leptons through a low mass mediator particle. We consider several varieties of this scenario depending on the type of mixing among gauge bosons and we study the implications in novel direct dark matter experiments for detecting low energy recoiling electrons. We find significant event rates and time modulation effects, especially in the case where the mediator is massless, that may be complementary to those from recoiling nuclei.

Heavy singlet fermionic dark matter with $Z_4$ symmetry
In the Z4-symmetric singlet fermionic DM model with a new scalar, viable heavy-DM parameter space in the secluded regime permits non-negligible Higgs mixing while satisfying relic density and direct detection bounds.
