Probing the decay A0⟶h0Z(∗) in Two‐Higgs‐Doublet Models in the Inverted Hierarchy Scenario at the Large Hadron Collider

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
Searches are being carried out at the Large Hadron Collider (LHC) for the decay of the CP‐odd scalar (A0) in two‐Higgs‐doublet models (2HDMs) with natural flavour conservation (NFC) in the channel A0⟶h0Z, where h0 is either the discovered 125 GeV Higgs boson or is an undiscovered CP‐even scalar with a mass below 125 GeV.

Neutrinos and Gamma Rays from Galaxy Clusters Constrained by the Upper Limits of IceCube

The Astrophysical Journal
Clusters of galaxies possess the capability to accelerate cosmic rays (CRs) to very high energy up to ∼10 ^18 eV due to their large size and magnetic field strength, which favor CR confinement for cosmological times.

Spectral Analysis of Flickering Gamma‐Ray Flashes Observed During the ALOFT 2023 Campaign

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract We examine a newly discovered category of high‐energy radiation events called flickering gamma‐ray flashes (FGF) detected during the airborne lightning observatory for FEGS and TGFs campaign in July 2023. These FGFs are characterized by highly pulsating gamma‐ray emissions that have no detectable concurrent optical or radio signals (Ostgaard ...

Supernova Neutrino Neutrino Astronomy

, 2018
Modern neutrino facilities will be able to detect a large number of neutrinos from the next Galactic supernova. We investigate the viability of the triangulation method to locate a core-collapse supernova by employing the neutrino arrival time differences at various detectors.

Quantification of Perturbation to the Daytime Lower Ionosphere From a Gamma Ray Burst Using ELF Remote Sensing

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract On 9 October 2022, a powerful gamma ray burst (GRB), GRB221009A, caused significant changes in the electron density of the lower ionosphere, as evidenced by VLF (3–30 kHz) radio wave observations. However, GRB221009A did not yield any observable signatures at the Schumann resonances (∼8, ∼14 Hz), which are also sensitive to the lower ...

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 ...
