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

Colonization and extinction lags drive non‐linear responses to warming in mountain plant communities across the Northern Hemisphere

Ecography, EarlyView.
Global warming is changing plant communities due to the arrival of new species from warmer regions and declining abundance of cold‐adapted species. However, experimentally testing predictions about trajectories and rates of community change is challenging because we normally lack an expectation for future community composition, and most warming ...

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 ...

Predicting habitat suitability of selected Meloidae species and future potential refugia: A case study from inner Western Anatolia

Insect Conservation and Diversity, EarlyView.
Consensus habitat‐suitability maps identify current hotspots of species richness across the Inner Western Anatolian mountain systems. Late‐century projections (2081–2100) under SSP2‐4.5 and SSP5‐8.5 show range shifts and changing richness patterns, intensifying at higher elevations.

A comprehensive study of ALPs from B-decays

Journal of High Energy Physics
We present a comprehensive study of axion-like particles (ALPs) through flavor changing neutral current processes, such as B → Ka followed by a → hadronic, γγ, μ + μ − channels. Our generic framework encompasses different ultraviolet scenarios similar to

Axion couplings to electroweak gauge bosons

European Physical Journal C: Particles and Fields, 2019
We determine the model-independent component of the couplings of axions to electroweak gauge bosons, induced by the minimal coupling to QCD inherent to solving the strong CP problem.

ALPINIST: Axion-Like Particles In Numerous Interactions Simulated and Tabulated

Journal of High Energy Physics, 2022
Proton beam dump experiments are among the most promising strategies to search for light and feebly interacting states such as axion-like particles (ALPs). The interpretation of these experiments is however complicated by the wide range of ALP models and

Endemic but not eroded: Genomic distinctiveness and conservation genomics of the British swallowtail butterfly (Papilio machaon britannicus)

Insect Conservation and Diversity, EarlyView.
Through whole‐genome sequencing of P. machaon populations across Europe, we demonstrate that P. m. britannicus forms a genetically distinct and isolated lineage. Demographic modelling revealed weak historical gene flow from the continent. Although P. m.

Pangenome analysis reveals the genetic mechanism underlying high‐altitude adaptation in Qinghai–Xizang (Tibet) Plateau Rhododendron

Journal of Integrative Plant Biology, EarlyView.
Pan‐genome analysis reveals that high‐altitude Rhododendron species resist alpine cold stress by rapidly sensing and engaging the chilling response pathway and genes that directly and indirectly protect the plant from UV radiation. Heritable genomic features such as long terminal repeats contribute to the adaptive diversification of Rhododendron ...

Classification of three-family flavoured DFSZ axion models that have no domain wall problem

Journal of High Energy Physics
We provide an exhaustive classification of three-family DFSZ axion models that have no cosmological domain wall problem. This result is obtained by making the Peccei-Quinn symmetry flavour dependent in certain specific ways, thus reinforcing a possible ...
