Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

The $$D_s^+ \rightarrow a_0(980) e^+ \nu _e$$ D s + → a 0 ( 980 ) e + ν e reaction and the $$a_0(980)-f_0(980)$$ a 0 ( 980 ) - f 0 ( 980 ) mixing

European Physical Journal C: Particles and Fields, 2021
We perform a study of the $$D_s^+ \rightarrow a_0(980)(f_0(980)) e^+ \nu _e$$ D s + → a 0 ( 980 ) ( f 0 ( 980 ) ) e + ν e reactions investigating the different sources of isospin violation which make the production of the $$a_0(980)$$ a 0 ( 980 ...

Correlation Patterns of Muon Flux With Vertical Atmospheric Profiles: Insights From Monte Carlo Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

Overlapping Land Tenure Stories: Ambiguity in Port Vila's Urban Precarity

City &Society, Volume 37, Issue 1, April 2025.
ABSTRACT Migrants to Port Vila from elsewhere in Vanuatu and the customary owners of the land to which they move make agreements about land tenure. However, land can hold multiple meanings which can both support and undermine attempts to create durable agreements.

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Anatomy of kaon decays and prospects for lepton flavour universality violation

Journal of High Energy Physics, 2022
The kaon sector is characterised by several processes which are under active investigation across different experiments. In this work, we present the global picture that emerges from a study of the different decay modes.
