Probing QCD Axions or axion-like particles in three-body K decays

Journal of High Energy Physics
Two-body decays like K → πa rank among the most constraining collider probes for new, low-mass, feebly interacting pseudoscalar particles a. We explore an alternative class of kaon decay modes, specifically three-body decays to ππa or μμa.

Mapping Italy's Sacred Natural Sites to Support the Establishment of Other Effective Area‐Based Conservation Measures (OECMs)

Journal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim Sacred natural sites (SNS) are culturally governed places that often retain remnants of natural vegetation, safeguard species of conservation concern and maintain landscape continuity, positioning them as potential Other Effective Area‐Based Conservation Measures (OECMs).

From supernovae to neutron stars: a systematic approach to axion production at finite density

Journal of High Energy Physics
We present a systematic study of QCD axion production in environments with finite baryon density and temperature, implying significant changes to axion phenomenology.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

QCD axion bubbles in the presence of ALP resonant conversion

Communications in Theoretical Physics
Abstract The QCD axion bubbles can form due to an explicit breaking of the Peccei–Quinn symmetry in the early Universe. In this paper, we investigate the modified formation of a QCD axion bubble in the presence of an axionlike particle (ALP), considering its resonant conversion to a QCD axion. We consider a general scenario where the QCD

Bounds on PBH fraction in a stimulated axion/ALP decay scenario

In this work, we show that stimulated decay of axions or axion-like particles (ALP) in black hole superradiance is an efficient way to find and hunt primordial black holes (PBH). When de Broglie's wavelength of the axion/ ALP is comparable or larger than the black hole horizon radius, a large population of them accumulates in the surroundings of the ...
