Model-independent reinterpretation of Belle II B+ → K+ νν̄ data using public kinematic mapping yields a factor-of-nine improvement on the limit for B+ → K+ a and constrains the axion's b-s flavor-changing coupling.
Pre-inflationary QCD axions form dense stars with densities up to 10^4 eV^4 that contain up to 50% of dark matter after moduli domination.
Reinterpretation of COMPASS data sets exclusion limits g_aγγ ≳ 10^{-1} GeV^{-1} at 95% CL for ALP masses 0.2-600 MeV by treating merged decay photons as contamination in the Compton sample.
Lattice QCD computations in thermal effective field theory yield sphaleron rates and axion production rates that deviate from perturbative estimates at high temperatures.
Proposes resonant detection of QCD axions (0.1-2.3 meV) and dark photons (down to epsilon ~2e-16) via highly excited electron cyclotron states in an open-endcap Penning trap compatible with large cavities.
Nelson-Barr mechanism yields ultralight scalar dark matter inducing time-periodic variation in CKM matrix elements, distinguishable from QCD axion and detectable via nuclear clocks.
QCD axions constrain F-theory base threefolds to have rigid or flux-rigidified divisors, yielding typical axion masses around 10^{-9} eV and decay constants near 10^{15} GeV in allowed regions.
Using S2 star periastron precession, the work constrains ultralight scalar dark matter mass ratios to below 10^{-3} or 1 and improves quadratic coupling bounds for masses 10^{-20} to 10^{-18} eV.
ℓ-boson stars are constructed and their properties studied in asymptotically anti-de Sitter spacetime.
Numerical and analytic modeling of boson star-black hole systems in the nonrelativistic limit, with Fisher analysis indicating LISA sensitivity to ultralight dark matter mass and self-coupling via gravitational wave dephasing.
In supersymmetric DFSZ axion models, the LHC with 140 fb^{-1} can probe axion decay constants below 10^{11} GeV for higgsino masses under 1 TeV via displaced neutralino decays to axino LSPs.
