We consider flavor constraints on, and collider signatures of, asymmetric dark matter (ADM) via higher dimension operators. In the supersymmetric models we consider, $R$-parity-violating (RPV) operators carrying $B-L$ interact with $n$ dark matter particles $X$ through an interaction of the form $W=X^n{\mathcal{O}}_{B-L}$, where ${\mathcal{O}}_{B-L}=q\ell d^c$, $u^c{d}^c{d}^c$, $\ell \ell e^c$. This interaction ensures that the lightest ordinary supersymmetric particle is unstable to decay into the $X$ sector, leading to a higher multiplicity of final state particles and reduced missing energy at a collider. Flavor-violating processes place constraints on the scale of the higher dimension operator, impacting whether the LOSP decays promptly. While the strongest limitations on RPV from $n-\overline{n}$ oscillations and proton decay do not apply to ADM, we analyze the constraints from meson mixing, $\mu -e$ conversion, $\mu \to 3e$ and $b\to s{\ell }^{+}{\ell }^{-}$. We show that these flavor constraints, even in the absence of flavor symmetries, allow parameter space for prompt decay to the $X$ sector, with additional jets and leptons in exotic flavor combinations. We study the constraints from existing 8 TeV LHC Supersymmetry (SUSY) searches with (i) 2–6 jets plus missing energy and (ii) 1–2 leptons, 3–6 jets plus missing energy, comparing the constraints on ADM-extended supersymmetry with the usual supersymmetric simplified models.
