We study the process of dark matter particles scattering off 3;4 He with nuclear wave functions computed using an ab initio many-body framework. We employ realistic nuclear interactions derived from chiral effective field theory at next-to-next-to-leading order (NNLO) and develop an ab initio scheme to compute a general set of different nuclear response functions. In particular, we then perform an accompanying uncertainty quantification on these quantities and study error propagation to physical observables. We find a rich structure of allowed nuclear responses with significant uncertainties for certain spin-dependent interactions. The approach and results that are presented here establish a new framework for nuclear structure calculations and uncertainty quantification in the context of direct and (certain) indirect searches for dark matter.

“…It is important to first notice that the Z gauge boson arising from the L µ − L τ local symmetry dictates a dark matter phenomenology rather different from other realizations of a "dark Z portal" (see e.g. [67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84]). For example, the dark matter pair annihilation exclusively yields muon, tau, and neutrino pairs, as well as Z boson pairs, if kinematically allowed (i.e.…”

We present a dark sector model based on gauging the L µ − L τ symmetry that addresses anomalies in b → sµ + µ − decays and that features a particle dark matter candidate. The dark matter particle candidate is a vector-like Dirac fermion coupled to the Z gauge boson of the L µ − L τ symmetry. We compute the dark matter thermal relic density, its pair-annihilation cross section, and the loop-suppressed dark matter-nucleon scattering cross section, and compare our predictions with current and future experimental results. We demonstrate that after taking into account bounds from B s meson oscillations, dark matter direct detection, and the CMB, the model is highly predictive: B physics anomalies and a viable particle dark matter candidate, with a mass of ∼ (5 − 23) GeV, can be accommodated only in a tightly-constrained region of parameter space, with sharp predictions for future experimental tests. The viable region of parameter space expands if the dark matter is allowed to have L µ − L τ charges that are smaller than those of the SM leptons.

Using a simplified framework, we attempt to explain the recent DAMPE cosmic e + + e − flux excess by leptophilic Dirac fermion dark matter (LDM). The scalar (Φ 0 ) and vector (Φ 1 ) mediator fields connecting LDM and Standard Model particles are discussed. We find that the couplings P ⊗ S, P ⊗ P , V ⊗ A and V ⊗ V can produce the right bump in e + + e − flux for a DM mass around 1.5 TeV with a natural thermal annihilation crosssection < σv >∼ 3×10 −26 cm 3 /s today. Among them, V ⊗V coupling is tightly constrained by PandaX-II data (although LDM-nucleus scattering appears at one-loop level) and the surviving samples appear in the resonant region, m Φ 1 2m χ . We also study the related collider signatures, such as dilepton production pp → Φ 1 → + − , and muon g −2 anomaly. Finally, we present a possible U(1) X realization for such leptophilic dark matter.
