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.
Revised supernova opacity modeling reopens the Turner window for hadronically coupled axions, enabling resonant absorption searches in NaI detectors for couplings |g_app| between 10^{-6.5} and 10^{-2}.
A segmented solenoid and external-resonator geometry reduces required magnetic energy for neV-scale axion searches while aiming to keep sensitivity intact.
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.
Proposes that axion-photon conversion in pre-CMB helical magnetic fields imprints detectable V-mode polarization in the CMB, allowing CLASS 40 GHz observations to constrain ALP masses 10^{-10} to 10^{-8} eV and their photon coupling under optimistic nG field assumptions.
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.
Photon-axion conversion near Kerr black holes produces dimming of photon spectral luminosity that increases with black hole spin, magnetic field strength, and photon-axion coupling, most efficiently at high frequencies.
A minimal electrophilic ALP portal for SIMP pion dark matter widens the allowed parameter space, making an ALP mass of order 10 MeV viable and consistent with the X17 anomaly.
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.
STCF can reach |V_eN|^2 values one to two orders of magnitude below current bounds for heavy neutral leptons via displaced-vertex searches from ALP decays in D-meson production.
Semi-analytic modeling of supernova cooling with six PNS parameters yields bounds on axion-nucleon coupling versus ALP mass that match numerical simulation results.
In a supersymmetric effective field theory the axion-like particle mass is generated predominantly by soft supersymmetry-breaking effects, producing a heavy ALP spectrum controlled by the SUSY-breaking scale.
Incorporating the KSVZ axion modifies the mass and electromagnetic charges of the Cho-Maison electroweak monopole through numerical solutions of the coupled equations with axion-photon interaction.
