Lattice simulations show axion misalignment production splits into two regimes during first-order phase transitions, unified by a semi-analytical relic density formula that also alters isocurvature and small-scale power spectrum.
A minimal dark matter model with one complex scalar carrying B and L numbers, stabilized by proton stability, with mass near the proton mass and relic density from UV freeze-in.
Bayesian model selection over SMEFT operator subsets using a genetic algorithm and BIC approximation is applied to electroweak, Higgs, top and diboson data, finding no evidence for new physics and improved Wilson coefficient posteriors compared to global fits.
A semiclassical tunneling model shows that two-field ultralight DM halos have stability bounds that can be relaxed for some density-mass ratios but become more stringent across much of the parameter space compared to single-field cases.
Paleo-detectors can achieve high sensitivity to sub-GeV dark matter boosted by cosmic rays and supernovae, covering previously inaccessible parameter space with orders of magnitude better reach than current experiments.
Dark pions stabilized by U(1) flavor symmetry in an SU(3)/SO(3) dark sector obtain the correct thermal relic density through up-scatterings to heavier mesons and dark eta decays, producing LHC signals from long-lived particle showers.
Non-equilibrium relativistic SIDM halo collapse produces seed black holes of mass ~3e-8 of the halo mass at apparent horizon formation.
No signal found in first search for eta to pi0 plus invisible dark scalar decay, setting branching fraction limits of (1.8-5.5)x10^-5 at 90% CL and improving DM-nucleon cross section bounds by ~5 orders of magnitude.
Tachyonic instabilities from post-inflation curvature reorganization via quadratic Gauss-Bonnet coupling produce the observed dark matter relic density across wide mass and scale ranges, backed by lattice simulations and a fitting function.
Bubble collisions in a seesaw model produce right-handed neutrinos that source novel gravitational waves detectable by LISA, ET, and LVK while allowing the lightest RHN to explain dark matter or enable leptogenesis.
Quadratic WIMP-ALP coupling induces coherent freeze-out that allows WIMP annihilation cross sections up to 1000 times larger than standard while matching relic density, plus an ALP miracle where Planck-suppressed couplings naturally yield correct ALP dark matter abundance independent of initial mass
Derives the power spectrum evolution and cross-spectra for arbitrary multi-species wave and particle dark matter, incorporating free-streaming, Jeans scales, and intrinsic fluctuations.
Presents a general analytic framework based on truncated BBGKY hierarchy solved via Volterra equations for computing power spectra in multi-species dark matter with finite velocity dispersion and Poisson fluctuations.
Sucrose crystals function as a phonon detector with scintillation for particle detection in sub-GeV dark matter searches.
Strongly interacting dark matter described by a first-principles G2 gauge-theory equation of state can be mixed into neutron stars while remaining compatible with current observational constraints.
ANTARES Galactic Ridge neutrino observations constrain DM-nucleon elastic scattering cross sections down to keV-scale DM masses via cosmic ray–dark matter deep inelastic scattering.
Presents a tensorized GPU implementation of the 2-to-2 elastic self-collision operator for dark-sector particles and applies it to a two-source freeze-in scenario where self-interactions erase bimodal features.
Curvaton self-interactions in non-quadratic potentials produce a local non-Gaussian map that enables supermassive primordial black hole formation at peak amplitudes of order 10^{-5} while remaining consistent with μ-distortion bounds.
Tentative double Gaussian excess at 1.59 GeV (2.6σ) and 11.15 GeV (3.7σ) in Fermi-LAT spectrum of blazar 4FGL J0604.9-0000, combined TS ≃ 27 (~4.3σ local).
One-loop weak corrections to fermionic MDM annihilation cross sections are computed, with IR divergences canceling in the s-wave and 5% effects in doublet, triplet, and quintuplet cases.
Non-Gaussian primordial fluctuations of a Z2-symmetric spectator scalar trigger a strong first-order electroweak phase transition, with the field serving as cold dark matter and generating a stochastic gravitational wave background in the 10^{-3}-10^{-1} Hz band.
Auriga simulations show the LMC induces azimuthal anisotropies in directional DM recoils that enhance discovery prospects relative to the Standard Halo Model.
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.
