The X and Gamma-Ray Imager and Spectrometer Onboard THESEUS—Status and Technological Progresses
Gamma-Ray Bursts (GRBs) are intense bursts of high-energy photons which, in just a few seconds, outshine all other γ-ray emitters in the sky. Due to their extreme luminosity, GRBs are not only important as high-energy astrophysical phenomena but also serve as valuable probe models of the far…

Projected Scalar Green Functions and Schur Reduction of PT-Symmetric Quaternionic Principal-Symbol Deformations
We study the Green function of a real scalar field ϕ+ on a fixed real Lorentzian spacetime (M,g). Quaternionic data enter only through a fixed auxiliary two-component representation of the scalar principal-symbol deformation Gμν=gμνI+δGμν, which is not a spacetime metric. The grading Θ selects the…

Polarization Resolved Dark Photon Radiation from Final State Leptons in D0 → e+e−A′
We investigate dark photon emission from the final state leptons in the rare decay D0→e+e−A′ within a point-like description of the parent transition. The physical electron mass and exact three-body kinematics are retained throughout the complete phase space for each dark photon mass in the…

The Potential of the THESEUS Mission for Studies of Young Stellar Objects
THESEUS is a proposed ESA M-class mission primarily designed for high-redshift gamma-ray burst studies, but its wide-field survey strategy and multi-instrument payload also offer significant opportunities for time-domain investigations of Galactic young stellar objects (YSOs). We assess the…

Elastic Scattering of 17Ne and 15O from 28Si
Elastic scattering angular distributions of 17Ne + 28Si at Elab=22.4 MeV/u and 15O + 28Si at Elab=18.2 MeV/u, well above the Coulomb barrier (Ecm/VB=9.7 and 8.2, respectively), have been measured at the HIRFL–RIBLL facility in Lanzhou. Time of flight–ΔE (TOF–ΔE) beam identification, PPAC-based…

Input Optics and Laser Frequency Noise Suppression for Einstein Telescope and Third-Generation Gravitational-Wave Detectors
Future gravitational-wave observatories such as Einstein Telescope and Cosmic Explorer will require a substantial evolution of the laser frequency stabilization strategies currently employed in second-generation interferometric detectors. In Advanced Virgo and Advanced LIGO, residual laser…

Modified Dispersion Relation in Kaluza–Klein Theory
In this study, corrections to the dispersion relation in Kaluza–Klein theory with one extra compactified spatial dimension were analyzed in a static, spherically symmetric case. The Ricci scalar curvatures of spacetime and phase space in the Einstein conformal frame were studied with respect to the…

Laser-Induced Fusion via Resonant Nanorod Antennas
Laser-driven proton acceleration in hydrogen-rich media can be strongly modified by embedded plasmonic nanoantennas that localize electromagnetic energy on nanometer scales. The National Ignition Facility (NIF) project at the Lawrence Livermore National Laboratory has achieved 8.6 MJ of fusion…

Exploiting the Latent Space of Deep AutoEncoders for the Identification of Signal Pulses in Noisy Time-Series
We propose a data-driven procedure, based on convolutional variational autoencoders, to identify the presence of signal pulses in long time series. The dataset consists of synthetic waveforms, each composed of non-Gaussian noise and a log-normal-shaped signal of variable intensity, with a length of…

Nexus-NRS (Nuclear Reaction Suite): Open Functional-Programming Software for Nuclear Reaction Modeling with DWBA—Design and Validation
Nexus-NRS is an open, reproducible software tool for nuclear reaction calculations, implemented in a functional-programming style (Clojure); the underlying reaction theory is standard and pre-established, and the contribution here is the software: stable radial solvers for weakly bound (halo)…

Stitching Algorithm for Improving ICARUS Track Reconstruction
The ICARUS experiment is part of the Short-Baseline Neutrino program at Fermilab and aims to search for the possible existence of sterile neutrinos in the O (1 eV) mass range, addressing anomalies observed by the LSND and MiniBooNE experiments. The ICARUS-T600 detector is a Liquid Argon Time…

Evaluation of an Experimental Technique for Measuring Charge-Changing Cross-Sections via Monte Carlo Simulations
Measurements of charge-changing cross-sections were developed as a method for determining proton radii, particularly for unstable, short-lived nuclei. Such cross-sections must be measured with high precision to determine the precise charge radii. However, there are complexities in the experimental…

High-Altitude Study of Coplanarity Phenomena in Superhigh-Energy EAS Cores with a Thick Calorimeter
The effect of a tendency toward coplanarity of sub-cores in gamma-ray–hadron families, observed in high-mountainous and stratospheric experiments with X-ray emulsion chambers at super-high energies, is discussed. Based on simulations within the framework of the traditional FANSY 2.0/QGSJ model and…

On the Stability of the Euler–Poisson Dark-Fluid Model
We present a stability analysis of a dark-fluid model described as a non-relativistic, rotating, non-viscous, self-gravitating fluid. We assume there is spherical symmetry and model the matter using a polytropic equation of state. The resulting coupled nonlinear partial differential equation system…

Latest Results from the ICARUS Experiment at the SBN Program
The ICARUS Collaboration is now entering its sixth year of continuing operations of the 760-ton liquid argon T600 detector. The T600 was overhauled at CERN after operations at the LNGS underground laboratory in Italy and moved to its present location at FNAL—as part of the Short-Baseline Neutrino…

Understanding Transversely Polarized Quarks Inside Longitudinally Polarized Nucleons
We review the current understanding of transversely polarized quarks inside longitudinally polarized nucleons from the perspective of the longi-transversity distribution function and transverse-momentum-dependent (TMD) factorization. Employing the recently developed TMD evolution formalism for the…

Primordial Black Hole Formation Beyond the Standard Cosmic QCD Transition
We review the role of primordial black holes (PBHs) for illuminating the dark ages of the cosmological evolution and as dark matter (DM) candidates. We elucidate the role of phase transitions for primordial black hole formation in the early Universe and focus our attention on the cosmological QCD…

Photoproduction of the Quarkonia Pairs in the CGC Framework
In this manuscript, we present the results of our studies on the exclusive photoproduction of quarkonium-photon pairs with large invariant mass. In our analysis, we focus on the production of the ηcγ and χcJγ pairs in high energy kinematics. We use the Color Glass Condensate (CGC) framework for…
