A 0.233 g silicon athermal phonon detector with 361.5 MeV/c² rms resolution sets the strongest direct-detection limits on dark matter-nucleon cross sections for masses 44–87 MeV/c² after 12 hours of exposure.
A framework unifies dark matter stability and proton decay via residual Z4 symmetry from U(1)B+L breaking, with one-loop proton decay mediated by TeV-scale dark sector particles whose masses correlate with proton lifetime.
LZ reports a null result from 4.2 tonne-year exposure and sets new world-leading upper limits on spin-independent WIMP-nucleon cross sections reaching 2.2e-48 cm2 at 40 GeV.
A gauged U(1)_{Lμ-Lτ} model generates nearly degenerate Majorana dark matter whose self-interactions via a light scalar mediator set the relic density, resolve core-cusp anomalies, and fit LZ direct detection plus muon g-2 bounds.
XENONnT extracted nuclear recoil light and charge yields in liquid xenon from 0.3 to 5 keV_NR using 474 events from a ⁸⁸YBe source after subtracting 55 background events.
A Z2-symmetric model with two singlet fermions and a singlet scalar yields viable multi-component dark matter where the scalar evades current direct detection bounds with minimal relic contribution while the fermions dominate the relic density with loop-suppressed scattering below the neutrino floor
Electroweak doublet dark matter with Higgs-portal interactions accounts for the Galactic halo gamma-ray excess via gauge boson annihilation and allows inelastic scattering with ~100 keV splitting.
