Effective field theories of axion, ALP and dark photon

Journal of High Energy Physics
A bstract With the help of Young tensor technique, we enumerate the complete and independent set of effective operators up to dim -8 for the extension of the standard model with a Goldstone boson by further imposing

The experimental challenge of detecting solar axion-like particles to test the cosmological ALP-photon oscillation hypotheses [PDF]

Astroparticle Physics, 2011
We consider possible experimental tests of recent hypotheses suggesting that TeV photons survive the pair production interaction with extragalactic background light over cosmological distances by converting to axion-like particles (ALPs) in galactic magnetic fields. We show that proposed giant ultra-low background scintillation detectors will even have

Beyond Spherical Harmonics: Rethinking Appearance Models for Radiance Reconstruction

Computer Graphics Forum, EarlyView.
Abstract View‐dependent appearance modeling remains a challenging problem in novel‐view synthesis and reconstruction. Accurately representing complex angular effects often requires substantial memory and computational resources. For new learning‐based methods, a common approach is to rely on Spherical Harmonics (SH).

The International Axion Observatory (IAXO) [PDF]

, 2011
The International Axion Observatory (IAXO) is a new generation axion helioscope aiming at a sensitivity to the axion-photon coupling of ga & few × 10−12 GeV−1, i.e. 1–1.5 orders of magnitude beyond the one currently achieved by CAST.

Small instantons and the post-inflationary QCD axion in a special product GUT

Journal of High Energy Physics
We present a new framework of grand unification that is equipped with an axion solution to the strong CP problem without a domain wall problem when the Peccei-Quinn (PQ) symmetry is spontaneously broken after inflation.

Synthesis of Pollinator‐Friendly Management in European Protected Areas

Conservation Biology, EarlyView.
Effectiveness of pollinator‐friendly management in European protected areas. Abstract Pollinators are important to humans and nature due to their role in ecosystem functioning and services. Research on the effects of pollinator management in protected areas is insufficient compared with that on farmlands and urban areas, potentially hindering ...

Electroweak precision test of axion-like particles

Journal of High Energy Physics, 2023
We study the contributions of an axion-like particle to the electroweak precision observables. The particle is assumed to couple with the standard model electroweak gauge bosons.

Taxonomic and functional patterns of arthropod succession after glacier retreat in the Dolomite Alps

Insect Conservation and Diversity, EarlyView.
Arthropod succession after glacier retreat varied among species and forelands in the Dolomites Alps, with community composition shaped by glacier identity, time since deglaciation and local environmental conditions. Functional composition shifted from small, highly dispersive pioneer species to larger, less dispersive taxa, reflecting increasing ...

Light Shining Through Wall Bounds on Axions From Obscured Magnetars

, 2023
Coupling of axions or axion-like particles (ALPs) with photons may lead to photons escaping optically opaque regions by oscillating into ALPs. This phenomenon may be viewed as the Light Shining through Wall (LSW) scenario.

Climate Shapes Elevational Gradients in Concentration, Composition, and Functional Diversity of Willow Metabolomes

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants produce broad spectra of metabolites comprising primary metabolites involved in core physiological processes and specialized metabolites mediating responses to biotic and abiotic stress. Understanding how these various components of the metabolome respond to different environmental pressures can help us to understand drivers of ...
