Sensitivity of the FCC-ee to decay of an axion-like particle into two photons
Journal of High Energy PhysicsThe decay of the Z boson into axion-like particles (ALP) at the Z-pole run of the proposed CERN FCC-ee collider is investigated. We perform a detailed study of final states with three photons or with a single photon and missing energy, yielding an ...

Longitudinal Variation in Riparian Spider Communities Along Near‐Natural Streams
Ecology and Evolution, Volume 16, Issue 10, October 2026.Applying the River Continuum Concept to riparian zones, this study examined how longitudinal gradients in five southwestern German streams affect spider communities. While alpha diversity remained stable, spider abundance increased downstream, and community and trait compositions shifted significantly along the watercourse. These findings highlight how

Shining Light into the Hidden Sector with ALPS II
, 2020 The strong CP problem, the existence of dark matter, the transparency of interstellar space to highly energetic photons, anomalies in stellar cooling rates, all of these phenomena suggest that our current understanding of the universe is incomplete ...

Solving the strong CP problem with massless grand-color quarks
Journal of High Energy PhysicsWe propose a solution to the strong CP problem that specifically relies on massless quarks and has no light axion. The QCD color group SU(3) c is embedded into a larger, simple gauge group (grand-color) where one of the massless, colored fermions enjoys ...

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.In a 100‐patient memory‐clinic cohort, DTI‐ALPS was evaluated along with diffusion and microstructural metrics. DTI‐ALPS correlated strongly with mode of anisotropy and orientation dispersion index, and moderately with T1/FLAIR ratio and diamagnetic susceptibility, indicating that DTI‐ALPS mainly reflects white‐matter diffusion complexity rather than ...

Axion-like particle (ALP) portal freeze-in dark matter confronting ALP search experiments
Journal of High Energy PhysicsA bstract The relic density of Dark Matter (DM) in the freeze-in scenario is highly dependent on the evolution history of the universe and changes significantly in a non-standard (NS) cosmological framework prior to Big Bang Nucleosynthesis (BBN). In this

Interplay of ALP couplings at a muon collider
Journal of High Energy PhysicsAxion-like particles can couple to Standard Model gluons, electroweak gauge bosons, and massive fermions. A future multi-TeV muon collider provides a favorable environment to probe axion-like particles through multiple production channels, including ...
