Query: Asymmetric dark matter, baryon asymmetry and lepton number violation   We study the effect of lepton number violation (LNV) on baryon asymmetry,
generated in the early Universe, in the presence of a dark sector with a global
symmetry $U(1)_X$, featuring asymmetric dark matter (ADM). We show that in
general LNV, observable at the LHC or in neutrinoless double beta decay
experiments, cannot wash out a baryon asymmetry generated at higher scales,
unlike in scenarios without such dark sector. An observation of LNV at the TeV
scale may thus support ADM scenarios. Considering several models with different
types of dark matter (DM), we find that the DM mass is of the order of a few
GeV or below in our scenario.
