Vacuum metastability from Axion-Higgs criticality

Journal of High Energy Physics
Self-organised criticality, realised through cosmological dynamics in the early universe, is an alternative paradigm for addressing the electroweak hierarchy problem.

Trait convergence under warming: drought tolerance, not thermal limits, mediates native–invader dynamics in alpine ecosystems

Oikos, EarlyView.
Climate warming and plant invasions jointly alter alpine ecosystems, but the mechanisms underlying these interactions remain unclear. A key to predicting ecosystem vulnerability is whether native and invasive species can sustain performance as conditions warm.

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.

The ALPs from the top: searching for long lived axion-like particles from exotic top decays

Journal of High Energy Physics, 2022
Abstract We propose a search for long lived axion-like particles (ALPs) in exotic top decays. Flavour-violating ALPs appear as low energy effective theories for various new physics scenarios such as t-channel dark sectors or Froggatt-Nielsen models. In this case the top quark may decay to an ALP and an up- or charm-quark.

Needle in a haystack: Holocene history of European larch in Central Europe revisited

PLANTS, PEOPLE, PLANET, EarlyView.
Defining nativity of species is crucial for their management. However, this is a complex task, especially for species that have been used and spread by humans for a long time. We combined paleoecological records with extensive genetic data to investigate the Holocene history of European larch—a common and economically important tree species in Central ...

Axion-like Particles from String Compactifications

, 2013
We review how axion-like particles (ALPs) naturally emerge in the low-energy effective field theory of string compactifications. We focus on the study of their mass spectrum and couplings, stressing that they depend on the mechanism used to fix the ...

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.
