Theory Calculations for LDMX and LOHENGRIN beyond Coherent Bethe-Heitler Scattering
Higher-order electromagnetic and hadronic contributions to dark photon bremsstrahlung have limited impact on signal and background predictions for LDMX and LOHENGRIN except for requiring an HCAL extension in LOHENGRIN...

Direct Detection of Millicharged Particles from Supernovae
Calculations show millicharged particles from supernovae can produce over 10 electron-recoil events per year in major detectors for millicharge 10^{-9} and sub-MeV to MeV masses, improving SN cooling bounds by up to a...

Macroscopic Quantum Interference in Dark Matter Wave Scattering with MICROSCOPE
Nested cylinders in MICROSCOPE act as a dark-matter-wave interferometer, producing rotation-modulated signals that yield leading constraints on quadratic DM-nucleon couplings for masses 10^{-3}--10^{-2} eV.

Caught in the Cosmic Web: Environmental Impacts on the Halo Substructure Boosts to Dark Matter Annihilation Signals
At fixed host-halo mass, filament halos show mass-dependent boost modulation from 15% suppression to 12% enhancement, walls are intermediate, and void halos are suppressed by 30-33% relative to the cosmic-mean prediction.

Linking Leptogenesis and Asymmetric Dark Matter: A Testable Framework for Neutrino Mass and the Matter-Antimatter Asymmetry
A leptogenesis framework generates both baryon asymmetry and asymmetric dark matter via heavy Majorana neutrino decays, enabling a TeV-scale seesaw with hierarchical couplings and testable spin-independent DM cross se...

Freeze-out and spectral running of primordial gravitational waves in viscous cosmology
Shear viscosity adds damping to primordial gravitational waves, producing an extra red tilt for constant viscosity-to-Hubble ratio and a k-dependent blue tilt from freeze-out in the electron-photon-baryon plasma with ...

Calibrating the SIDM Gravothermal Catastrophe with N-body Simulations
N-body simulations with Arepo calibrate the β parameter in the SIDM gravothermal model, showing it is independent of cross-section, concentration, and mass for velocity-independent scattering, and introduce an effecti...

Probing inelastic sub-GeV dark matter at the DUNE near detector
DUNE's ND-LAr can probe sub-GeV inelastic dark matter parameter space consistent with relic abundance via dark Higgs-mediated annihilation, especially at large dark photon-to-DM mass ratios.

Cornering MeV-GeV Axions and Dark Photons with LDMX
LDMX can close much of the sub-100 MeV blind spot for axions and dark photons via charged track and momentum reconstruction.

Low-energy threshold demonstration for dark matter searches in TREX-DM with an $^{37}$Ar source produced at CNA HiSPANoS
TREX-DM detected 2.82 keV and 270 eV emissions from a 37Ar source produced at CNA HiSPANoS, demonstrating an energy threshold approaching single-electron ionization in argon for dark matter searches.

Searching for dark photons in $J/\psi$ decays
NRQCD calculations predict low event yields (0-172) and poor significances (10^{-6} to 10^{-1}) for dark photon mediated J/ψ decays at BESIII, with four-body invisible channels offering relatively better prospects bel...
