“…For smaller splittings and DM masses below a few GeV, we find that monophoton + missing momentum searches at Belle II could provide complementary sensitivity in this regime [96]. Finally, we comment that significant strong sensitivity could be achieved for m DM few GeV and small splittings with new electron beam-dump and active-target experiments [61,67,97,120,121], proposed proton-beam fixed target experiments [122][123][124], and future direct detection experiments [3] optimized for low threshold sensitivity. In this Appendix, we summarize the relevant cross sections and rates for the thermal relic abundances computed in Sec.…”

Dark Matter particles with inelastic interactions are ubiquitous in extensions of the StandardModel, yet remain challenging to fully probe with existing strategies. We propose a series of powerful searches at hadron and lepton colliders that are sensitive to inelastic dark matter dynamics. In representative models featuring either a massive dark photon or a magnetic dipole interaction, we find that the LHC and BaBar could offer strong sensitivity to the thermal-relic dark matter parameter space for dark matter masses between ∼ 100 MeV-100 GeV and fractional mass-splittings above the percent level; future searches at Belle II with a dedicated monophoton trigger could also offer sensitivity to thermal-relic scenarios with masses below a few GeV. Thermal scenarios with either larger masses or splittings are largely ruled out; lower masses remain viable yet may be accessible with other search strategies.

We describe an approach to detect dark matter and other invisible particles with mass below a GeV, exploiting missing energy-momentum measurements and other kinematic features of fixedtarget production. In the case of an invisibly decaying MeV-GeV-scale dark photon, this approach can improve on present constraints by 2-6 orders of magnitude over the entire mass range, reaching sensitivity as low as 2 ∼ 10 −14 . Moreover, the approach can explore essentially all of the viable parameter space for thermal or asymmetric dark matter annihilating through the vector portal.

“…A potentially promising direction is to use proton fixed-target experiments to probe DM couplings to quarks [10][11][12][13][14][15] (other proposals for light DM searches have been explored in [16][17][18][19][20][21][22][23][24][25][26][27]). An interesting type of mediator is a leptophobic Z boson.…”

High-intensity neutrino beam facilities may produce a beam of light dark matter when protons strike the target. Searches for such a dark matter beam using its scattering in a nearby detector must overcome the large neutrino background. We characterize the spatial and energy distributions of the dark matter and neutrino beams, focusing on their differences to enhance the sensitivity to dark matter. We find that a dark matter beam produced by a Z boson in the GeV mass range is both broader and more energetic than the neutrino beam. The reach for dark matter is maximized for a detector sensitive to hard neutral-current scatterings, placed at a sizable angle off the neutrino beam axis. In the case of the Long-Baseline Neutrino Facility (LBNF), a detector placed at roughly 6 degrees off axis and at a distance of about 200 m from the target would be sensitive to Z couplings as low as 0.05. This search can proceed symbiotically with neutrino measurements. We also show that the MiniBooNE and MicroBooNE detectors, which are on Fermilab's Booster beamline, happen to be at an optimal angle from the NuMI beam and could perform searches with existing data. This illustrates potential synergies between LBNF and the short-baseline neutrino program if the detectors are positioned appropriately.
