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.

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.

Coherent Detection of Ultra-weak Electromagnetic Fields

, 2018
We explore the application of heterodyne interferometry for a weak-field coherent detection scheme. The methods detailed here will be used in ALPS II, an experiment designed to search for weakly-interacting, sub-eV particles.

Duration of Classicality of Homogeneous Condensates with Attractive Interactions [PDF]

, 2017
Dark matter axions and other highly degenerate bosonic fluids are commonly described by classical field equations. In a recent paper \cite{BECprop} we calculated the duration of classicality of homogeneous condensates with attractive contact interactions

Primary metabolites in root exudates are not affected by long‐term soil warming in a temperate forest

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Primary metabolites in root exudates are essential for plant nutrition and rhizosphere microbiome function, potentially responding sensitively to climate warming. However, the effects of long‐term soil warming on exudate metabolites in forests remain unclear.

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 ...

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

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Top Secrets: long-lived ALPs in top production

Journal of High Energy Physics, 2023
We investigate the discovery potential for long-lived particles produced in association with a top-antitop quark pair at the (High-Luminosity) LHC. Compared to inclusive searches for a displaced vertex, top-associated signals offer new trigger options ...

Looking for dark matter on the light side

, 2014
Among the prominent low-mass dark matter candidates is the QCD axion but also other light and weakly interacting particles beyond the Standard Model. We review briefly the case for such dark matter and give an overview on most recent experimental efforts
