2092 papers

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.

Topological analysis of scale-invariant spatial fluctuations in ultrarelativistic heavy-ion collisions

This paper presents a novel two-stage topological machine learning framework that combines Topological Data Analysis with deep learning to successfully isolate weak critical fluctuation signals from overwhelming non-critical backgrounds in ultrarelativistic heavy-ion collisions, thereby restoring power-law scaling and enabling the reliable identification of the QCD critical point.

QCD Sum Rule Analysis of Triply Heavy (QQˉ)(Qqˉ)(Q\bar{Q})(Q\bar{q}) Tetraquark States with JP=0±J^P=0^{\pm}

Using QCD sum rules, this study systematically investigates the mass spectra and decay patterns of triply heavy (QQˉ)(Qqˉ)(Q\bar{Q})(Q\bar{q}) tetraquark states with JP=0±J^P=0^{\pm}, predicting specific mass ranges for charmed and bottomed systems and identifying which candidates are likely to be narrow enough for experimental detection.

SuperEM: A Sub-meV Threshold Detector Architecture for Cosmic Neutrino Background and Dark Matter Detection

This paper introduces the Superconductor-Coupled Semiconductor Electron-Multiplying (SuperEM) detector, a novel architecture that overcomes the traditional trade-off between sub-meV energy thresholds, fast timing, and scalability to enable the direct detection of the Cosmic Neutrino Background and sub-GeV Light Dark Matter.

Event Generators for High-Energy Physics Experiments

This paper provides an overview of the current status and future directions of Monte-Carlo event generators for high-energy physics, emphasizing the need for cohesive development, model tuning to experimental data, and open data preservation to reduce systematic uncertainties and ensure consistency across experiments.

Reconstruction of atmospheric neutrinos in DUNE's horizontal-drift far-detector module

This paper demonstrates that incorporating full hadronic system information, rather than just lepton data, significantly improves the reconstruction resolution of atmospheric neutrino direction and energy in DUNE's horizontal-drift liquid argon time projection chamber, establishing a foundation for future oscillation sensitivity analyses.

A 1-bit quantum filter for particle trajectory reconstruction

This paper introduces the 1-Bit Quantum Filter, a resource-efficient quantum algorithm that reformulates particle tracking as binary ground-state filtering to achieve O(Nlog⁡N)O(\sqrt{N} \log N) gate complexity, enabling realistic LHC event reconstruction on current Noisy Intermediate Scale Quantum (NISQ) hardware.
