Cosmological bounds on pseudo Nambu-Goldstone bosons

, 2012
We review the cosmological implications of a relic population of pseudo Nambu-Goldstone bosons (pNGB) with an anomalous coupling to two photons, often called axion-like particles (ALPs).

Quantifying the Rapid Propagation of Rainfall and Evapotranspiration Signals Into Soils

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Precipitation and evapotranspiration are major drivers of soil moisture dynamics, which in turn influence plant water availability, biogeochemical reactions, and trace gas emissions. However, it has been unclear whether evapotranspiration signals propagate through soil columns differently than precipitation signals do.

Aiming for tops of ALPs with a muon collider

Journal of High Energy Physics
Future muon colliders with center-of-mass energy of O $$ \mathcal{O} $$ (1 − 10) TeV can provide a clean high-energy environment with advantages in searches for TeV-scale axion-like particles (ALPs), pseudo-Nambu-Goldstone bosons associated with ...

Stellar Evolution Bounds on the ALP-Photon Coupling: new Results and Perspectives

, 2014
Stellar evolution considerations are of fundamental importance in our understanding of the axion/ALP-photon coupling, g_{a\gamma}. Helium burning stars are the best laboratories to study this coupling. Here, we will review the bounds from massive and low

Frost Tolerance Increases With Plant Height Among Co‐Occurring Alpine Species in the Central Tibetan Plateau

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Frost tolerance (LT50) varies greatly among species coexisting in an alpine community. Taller plants are more frost‐tolerant, reversing the expected intra‐community pattern. Evidence for a frost survival trade‐off: avoidance in short plants vs. tolerance in tall plants.

High quality QCD axion via electric-magnetic duality

Journal of High Energy Physics
We propose a novel paradigm for the QCD axion with high-quality Peccei-Quinn (PQ) symmetry on the basis of electric-magnetic duality in the conformal window of a supersymmetric gauge theory.

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up

Heavy QCD axions at high-energy muon colliders

Journal of High Energy Physics
We study the physics potential of heavy QCD axions at high-energy muon colliders. Unlike typical axion-like particles, heavy QCD axions solve the strong CP problem with phenomenology driven by the anomalous gluon aG G ~ $$ \left( aG\overset{\sim }{G ...

Mississippi State Axion Search: A Light Shining though a Wall ALP Search

, 2014
The elegant solutions to the strong CP problem predict the existence of a particle called axion. Thus, the search for axion like particles (ALP) has been an ongoing endeavor.

Beyond Co‐Occurrence: Multi‐Scale Evidence for Segregation‐Dominated Plant Networks in the French Alps

Ecology Letters, Volume 29, Issue 5, May 2026.
Using high‐resolution spatial data and a multi‐scale statistical framework, we disentangle plant co‐occurrence from true spatial associations across alpine communities in the French Alps. We discovered that local species associations are dependent on soil acidity and nitrogen rather than temperature. By building a global network from these associations,
