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.

Detection of Gravitational Anomaly at Low Acceleration from a Highest-quality Sample of 36 Wide Binaries with Accurate 3D Velocities

This study analyzes a high-quality sample of 36 wide binary stars with accurate 3D velocities to detect a significant gravitational anomaly at low accelerations, revealing a gravity boost factor of approximately 1.6 that rules out standard Newtonian dynamics and exceeds MOND predictions, a result primarily driven by two specific binary systems exhibiting unbound relative velocities.

Search for nonresonant triple Higgs boson production in the final state with six bottom quarks in proton-proton collisions at s\sqrt{s} = 13 TeV

Using 138 fb−1^{-1} of proton-proton collision data at s\sqrt{s} = 13 TeV collected by the CMS experiment, this study reports the first observation of nonresonant triple Higgs boson production limits, setting the most stringent constraints to date on the trilinear and quartic Higgs coupling modifiers and excluding a portion of the parameter space allowed by perturbative unitarity.

Benchmarking Nucleon Production in Hadron Interactions Relevant for GeV-scale Neutrino Experiments

This paper utilizes the GENIE neutrino event generator to benchmark nucleon production predictions from hadron-nucleus scattering models (Geant4 Bertini Cascade and INCL++) for GeV-scale neutrino experiments, deriving parameterized relationships and reweighting tools to address model uncertainties in final-state nucleon multiplicities and visible energy.

Leveraging Industrial Foundation Models at the Edge of Particle Physics Detectors via Distillation Learning and Hardware Co-design

This paper presents the first fine-tuning of Google's TimesFM foundation model for particle physics data acquisition, demonstrating that distilling it into a compact student model and co-designing it with FPGA hardware enables real-time, high-performance regression tasks on detector edge devices that surpass existing AI/ML solutions.
