Broad axion resonances: Clockwork ALPs at hadron colliders

Physical Review D
Scenarios with multiple pseudoscalars are interesting as they usually tend to provide a framework to naturally realize a light axion with a large decay constant which has rich applications in cosmology, especially in the context of inflation and light dark matter physics. On the other hand, from a particle physics perspective, this

Woody Vegetation Dynamics Beyond the Treeline: Identifying Limiting Processes and Their Tipping Points

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Illustration of temporal trends in Arctic and alpine woody vegetation under changing growth conditions (summer temperature and winter snowpack). Upper panel: example of shrub expansion in southern France (photograph included). Greening is detected via increasing NDVI (Normalized Difference Vegetation Index).

Exploring interference effects between two ALP effective operators at the LHC

Journal of High Energy Physics
We observe that most studies of axion-like particle (ALP) production channels at the Large Hadron Collider (LHC) focus on a single type of ALP operator for each process in the effective field theory framework.

MRI Diffusion Tensor Image Analysis Along the Perivascular Space: Effects of Mean Tract Orientation Divergence

Journal of Magnetic Resonance Imaging, Volume 64, Issue 3, Page 815-829, September 2026.
ABSTRACT Background The diffusion tensor image analysis along the perivascular space (DTI‐ALPS) index is an established term, and ongoing research aims to explore underlying mechanisms. Hypothesis DTI‐ALPS measures are influenced by subject‐specific orientational differences of the projection and association fibers. Study Type Prospective.

ALP leptogenesis: non-thermal right-handed neutrinos from axions

Journal of High Energy Physics
A bstract We propose a novel realisation of leptogenesis that relies on the out-of-equilibrium decay of an axion-like particle (ALP) into right-handed Majorana neutrinos (RHNs) in the early Universe.

Axion detection via superfluid 3He ferromagnetic phase and quantum measurement techniques

Journal of High Energy Physics
We propose to use the nuclear spin excitation in the ferromagnetic A1 phase of the superfluid 3He for the axion dark matter detection. This approach is striking in that it is sensitive to the axion-nucleon coupling, one of the most important features of ...

Resolving Taxonomic Boundaries in the New Zealand Senecio matatini Complex (Senecioneae, Asteraceae): Evidence from Genotyping by Sequencing of Limestone‐Associated Forms

New Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
The Senecio matatini complex in New Zealand has a convoluted taxonomic and nomenclatural history that has not been fully resolved. This is largely due to the incomplete sampling of morphologically diverse but highly threatened limestone populations in the eastern South Island in previous genetic studies.
