“…The shaded region is excluded by existing constraints. The constraints shown are from limits on π 0 → γ + invisible [6], J/Psi → invisible [7] and pp → jet + invisible (labeled monojet) [8], dark force searches by MAMI, BaBar, APEX and KLOE (labeled as e + e − ) [5], excessive contributions to electron and muon g-2 [9,10,11,12,13], a monophoton search by BaBar (labeled BaBar sensitivity) [14,15,16] and deviations in precision SM measurements [17]. The right-hand plot also features the best limits published by XENON10 [18], DAMIC [19], CDMSlite [20], XENON100 [21], and LUX [22] as of March 2014.…”

Low mass dark matter theories, if produced as a thermal relic in the early universe, must be accompanied by light mediators in order to obtain the dark matter abundance observed in the present day universe. These light mediators in turn provide a channel for the production of dark matter at fixed target neutrino experiments, producing a relativistic dark matter beam, which could then be detected by neutral-current-like interactions in neutrino detectors. We consider the possibility that fixed target neutrino experiments such as MiniBooNE and T2K could serve as a new dark matter search avenue, sensitive to sub-GeV dark matter scenarios that would be otherwise undetectable. These experiments are found to provide sensitivity to light stable states that could serve as viable candidates for particle dark matter.

“…For lower mass DM, the strongest constraints follow from limits on anomalous scattering at proton and electron fixed-target experiments such as LSND [413][414][415] and E137 [416,417], and on proton beam dump measurements with MiniBooNE [418]. For specific mass ranges, limits on invisible pion [419], kaon [420,421] and J/Ψ [422] decays are also significant.…”

Abstract. We present an overview of scenarios where the observed Dark Matter (DM) abundance consists of Feebly Interacting Massive Particles (FIMPs), produced non-thermally by the so-called freeze-in mechanism. In contrast to the usual freeze-out scenario, frozen-in FIMP DM interacts very weakly with the particles in the visible sector and never attained thermal equilibrium with the baryon-photon fluid in the early Universe. Instead of being determined by its annihilation strength, the DM abundance depends on the decay and annihilation strengths of particles in equilibrium with the baryon-photon fluid, as well as couplings in the DM sector. This makes frozen-in DM very difficult but not impossible to test. In this review, we present the freeze-in mechanism and its variations considered in the literature (dark freeze-out and reannihilation), compare them to the standard DM freeze-out scenario, discuss several aspects of model building, and pay particular attention to observational properties and general testability of such feebly interacting DM.

“…This implies that the shaded region labelled "Υ" in figure 1 is excluded. Similarly (except for the different electric charge of c and b quarks), a limit for M Z near 3 GeV arises from J/ψ decays, with the limit on invisible branching fraction given by B(J/ψ → invisible) < 7 × 10 −4 [49].…”

GeV-scale dark matter: production at the Main Injector

Assuming that dark matter particles interact with quarks via a GeV-scale mediator, we study dark matter production in fixed target collisions. The ensuing signal in a neutrino near detector consists of neutral-current events with an energy distribution peaked at higher values than the neutrino background. We find that for a Z boson of mass around a few GeV that decays to dark matter particles, the dark matter beam produced by the Main Injector at Fermilab allows the exploration of a range of values for the gauge coupling that currently satisfy all experimental constraints. The NOνA near detector is well positioned for probing the presence of a dark matter beam, and future LBNF near detectors would provide more sensitive probes.
