This paper establishes a full optical transfer function model for X-ray beam-tracking microscopy and experimentally validates it, demonstrating that the technique achieves a spatial resolution of at least 3 µm—significantly surpassing the aperture size—and formally confirming the anomalously high sharpness of its dark-field channel.
This paper presents Simphony, a GPU-accelerated optical photon Monte Carlo tool that achieves a ~1000-fold speedup over Geant4 while maintaining subpercent accuracy in photon detection metrics, thereby enabling practical large-scale optical simulations for noble liquid detector development and machine learning applications.
The paper introduces CaloTrilogy, a unified framework that achieves high-quality, physics-guided particle shower generation for modern calorimeters in just one or a few inference steps by combining an average velocity field integrator, a data-derived generative prior, and training-time physics constraints, thereby overcoming the computational inefficiencies of existing flow and diffusion models.
This paper proposes a parasitic high-energy polarized gamma-ray facility at FCC-ee using Compton backscattering to achieve a four- to seven-fold improvement in precision for measuring the polarized gluon distribution in the medium- region through open-charm photoproduction.
This paper presents a rapid, low-background liquid scintillation assay using pulse-shape analysis that efficiently measures Pb in archaeological lead with high sensitivity, enabling direct verification of secular equilibrium and serving as a reliable tool for radiopurity screening in rare-event physics experiments.
This paper presents preliminary measurements of Earth's angular velocity using TRIO, a new transportable ring laser gyroscope prototype with a 1.52 m side length, to evaluate its performance and validate the design for the upcoming large-scale GINGER project at the Gran Sasso underground laboratory.
This paper proposes an enhanced recursive gated cyclic residual-sparse linear attention network for CLYC detectors that achieves high-accuracy neutron-gamma pulse shape discrimination (98.7% accuracy, 2.2 quality factor) with robust noise resistance and ultra-low latency (0.05 ms) suitable for real-time embedded deployment.
This paper presents a spectrally resolved study of x-ray parametric down-conversion at the diamond K-edge, demonstrating pronounced polaritonic hybridization that achieves strong coupling and enables high-resolution extraction of the bulk diamond refractive index.
This paper presents an optimized Metropolis-Hastings algorithm and an inverse distance weighting approach to improve 3D density reconstruction and air-rock interface mapping in muography, demonstrating significantly enhanced accuracy and artifact reduction through both Monte Carlo simulations and field data from the TianQin Tunnel experiment.
This paper presents a simplified analytical and numerical model to quantify the maximum space-point resolution gains achievable through charge sharing in silicon pixel detectors with digital readout, deriving a phenomenological parameterization validated against experimental data from various detector technologies.
