“…A 70 eV threshold was achieved exploiting the Neganov-Trofimov-Luke (NTL) effect at high bias voltage (HV) to convert charge into heat; results for masses down to 1.5 GeV were presented from different analyses [36,37]. Data have been reanalyzed considering Bremsstrahlung radiation and the Migdal Effect, which allows to explore masses down to 30 MeV [38]. Very small Si detectors (0.93 and 10.6 g) have been operated on surface considering nucleon and electron scattering and dark photons [39,40].…”

Dark matter particles populating our galactic halo could be directly detected by measuring their scattering off target nuclei or electrons in a suitable detector. As this interaction is expected to occur with very low probability and would generate very small energy deposits, the detection is challenging; the possible identification of distinctive signatures (like an annual modulation in the interaction rates or directionality) to assign a dark matter origin to a possible observation is being considered. Here, the physics case of different dark matter direct detection experiments will be presented and the different and complementary techniques which are being applied or considered will be discussed, summarizing their features and latest results obtained. Special focus will be made on TPC-related projects; experiments using noble liquids have presently a leading role to constrain interaction cross sections of a wide range of dark matter candidates and gaseous detectors are very promising to explore specifically low mass dark matter as well as to measure directionality.

“…( 26)). The brown region, which also does not change across the pan-els, is the upper bound from direct detection searches at SuperCDMS [90], Xenon-1T [91], DarkSide-50 [92], and PandaX-4T [5]. These limits are obtained from the spin-independent r-exchange; the spin-dependent ALP exchange is Q 4 -suppressed and yields much weaker limits.…”

Scattering interactions between dark matter and Standard Model states mediated by pseudoscalars are generically challenging to uncover at direct detection experiments due to rates suppressed by powers of the local dark matter velocity vDM ∼ 10 −3 c. However, they may be observed in the dark matter-induced heating of neutron stars, whose steep gravitational potentials prevent such suppression by accelerating infalling particles to semi-relativistic speeds. We investigate this phenomenon in the context of two specific, self-consistent scenarios for pseudoscalars coupled to dark matter, and compare the sensitivity of neutron star heating to bounds from direct searches for the mediators and dark matter. The first "lighter" scenario consists of sub-10 GeV mass dark matter mediated by an axion-like particle (ALP), while the second "heavier" scenario has dark matter above 10 GeV mediated by a dark pseudoscalar that mixes with a pseudoscalar from a two-Higgs doublet (the so-called 2HDM+a model). In both frameworks, we show that imminent measurements of neutron stars will be able to test pseudoscalar-mediated dark matter beyond the reach of direct dark matter searches as well as bounds on the mediators from flavor observables, beam dump experiments, and high-energy colliders.

“…As such the Migdal manifests itself as an NR causing an electronic recoil (ER). While it has not been experimentally confirmed, it offers the possibility for experiments to extend their JCAP10(2022)004 DM search region to lower WIMP masses [13][14][15][16][17][18] since NRs that fall below the NR energy threshold of an experiment may result in detectable ERs.…”

Dark Matter experiments searching for Weakly interacting massive particles (WIMPs) primarily use nuclear recoils (NRs) in their attempt to detect WIMPs. Migdal-induced electronic recoils (ERs) provide additional sensitivity to light Dark Matter with 𝒪(GeV/c 2) masses. In this work, we use Bayesian inference to find the parameter space where future detectors like XENONnT and SuperCDMS SNOLAB will be able to detect WIMP Dark Matter through NRs, Migdal-induced ERs or a combination thereof. We identify regions where each detector is best at constraining the Dark Matter mass and spin independent cross-section and infer where two or more detection configurations are complementary to constraining these Dark Matter parameters through a combined analysis.
