Inflaton-gluon coupling during inflation requires p=2 plateau models to produce isocurvature-free QCD axion dark matter.
Magnetic reconnection in neutron stars drives transient axion bursts by exciting mixed Alfvén-axion modes in a non-ideal axion MHD framework.
ALPS II reports no detection of axion-like particles and establishes improved 95% CL upper limits on di-photon couplings of 1.5e-9 GeV^-1 for masses below 0.1 meV, plus limits for scalar, vector, and tensor bosons.
Light new particles generate asymmetries in e+e- to tau+tau- that allow model-dependent constraints on tau dipole moments, including non-zero effects without electron polarization via imaginary parts.
The Landau-Zener approximation for axion-photon conversion in neutron star magnetospheres fails when resonance width exceeds conversion region size, leading to revised axion constraints from optical-band searches.
Spectral features of primordial gravitational-wave backgrounds can directly reconstruct the mass and decay rate of long-lived BSM particles via the frequencies imprinted by an early matter-dominated epoch.
Electroweak-symmetric domain walls produce the observed baryon asymmetry when CP-odd sources and the hierarchy of wall, source, and diffusion lengths suppress face-to-face cancellation.
This work provides a comprehensive analysis of light new physics contributions to tau lepton dipole moments, detailing interpretations of asymmetry measurements for spin-0 and spin-1 bosons, their decoupling to the EFT limit, and a case study of a tauphilic vector boson at Belle II.
Lattice simulations of Abelian-Higgs cosmic strings with axion-gauge coupling show multimodal axion production that can account for GeV-scale dark matter while predicting observable dark radiation.
A proposed Chinese charm factory could detect heavy neutral leptons from axionlike-particle decays with a displaced-vertex search, reaching electron-neutrino mixing one to two orders of magnitude below current bounds.
Incorporating non-local gravitational self-energy from a T-duality-inspired model yields a regular neutral black-hole metric with extremal Planck-mass particle-black-hole solutions that are thermodynamically stable and suggested as dark matter.
