Hep-Ex explores the fascinating intersection where particle physics meets experimental reality. This field investigates how scientists build massive detectors and accelerate particles to test the fundamental laws of nature, turning abstract theories into measurable data. It is the rigorous process of searching for new particles or forces that could reshape our understanding of the universe, often requiring years of collaboration and engineering.
At Gist.Science, we ensure these discoveries become accessible to everyone. We process every new preprint in this category directly from arXiv, generating both plain-language explanations for curious readers and detailed technical summaries for specialists. Our goal is to bridge the gap between complex experimental results and public understanding without losing scientific nuance.
Below are the latest papers in Hep-Ex, freshly summarized and ready for you to explore.
This paper presents the first successful implementation and validation of GPU-accelerated optical photon simulation using Opticks for the 10-kiloton DUNE far-detector, demonstrating a speedup of up to 313 times over CPU-based GEANT4 while maintaining full Monte Carlo fidelity to enable high-statistics studies and machine learning dataset generation.
This paper introduces Masked Particle Modeling (MPM), a self-supervised pre-training framework that learns permutation-invariant representations of unordered particle sets in high energy physics by reconstructing masked particles via vector quantization, demonstrating its effectiveness as a foundation model for diverse downstream tasks like jet classification and domain transfer.
This paper presents an updated analysis of Borexino Phase-III data that establishes tighter constraints on flavor-diagonal non-standard neutrino interactions than previous studies and, for the first time, provides a comprehensive exploration of the full parameter space including off-diagonal NSI terms.
This paper demonstrates that joint model-and-data scaling laws derived from small transformer models can accurately predict the performance of significantly larger particle physics foundation models before training, enabling the translation of compute budgets into expected physics outcomes and validating the approach against state-of-the-art benchmarks.
This study presents a comparative analysis of DC electrical breakdown distributions in liquid nitrogen, helium, and argon using a unified experimental setup, revealing that breakdown strength is governed by a combination of thermodynamic stability against bubble formation and the transport properties of dominant charge carriers, while highlighting distinct behaviors such as liquid argon's non-stationary "turn-on" effect and liquid helium's bimodal distribution near saturation.
This paper projects the sensitivity of the InDEx experiment's superheated target to sub-GeV dark matter via electron scattering, demonstrating that by lowering operating temperatures to achieve thresholds as low as 26.8 eV, the experiment can probe dark matter masses down to approximately 12 MeV and set competitive upper limits on dark-photon-mediated scattering cross sections.
This paper introduces ADoNIS, a fully differentiable neutrino interaction event generator that enables exact gradient propagation through complex nuclear and scattering processes, thereby facilitating more efficient and precise physics analyses, model tuning, and experimental design without sacrificing physical fidelity.
This paper demonstrates that unshielded Kinetic-Inductance Traveling-Wave Parametric Amplifiers (KTWPAs) can maintain high gain (>20 dB) over multi-GHz bandwidths in multi-Tesla magnetic fields when oriented parallel to the field, offering a viable solution for quantum-limited signal amplification in strong-field environments like axion dark matter searches where traditional Josephson-based amplifiers fail.
Using 140 fb⁻¹ of proton-proton collision data at 13 TeV collected by the ATLAS detector, this paper presents the first measurement of the inclusive and differential cross-sections for the process in the trilepton channel, finding results consistent with Standard Model predictions and setting constraints on dimension-6 effective field theory operators.
This paper reports the successful development, commissioning, and characterization of a gram-scale cryogenic CaWO target-detector module for the NUCLEUS experiment, which achieved state-of-the-art energy resolution and demonstrated readiness for the upcoming Technical Run at the Chooz nuclear power plant.
