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 initiates a precision study of boosted jet substructure using energy correlators applied to hadronic Higgs decays, demonstrating that the two-body decay manifests as a distinct angular peak and that infrared scales like the dead-cone effect and confinement transition are resolvable, thereby enabling precision electroweak studies and new physics searches.
This paper presents PNNL's development and first demonstration of a tunable array of matched centimeter-scale cavities designed to overcome volume and sensitivity limitations for detecting axion dark matter in the 100 micro-eV mass range.
Using BESIII data collected at center-of-mass energies of 4.84, 4.92, and 4.95 GeV, no significant signal for the exotic charmonium-like state was observed in the process , leading to the establishment of 90% confidence level upper limits on the relevant production cross-sections.
This paper utilizes Bayesian thermal analysis of hadron yields from STAR Ru+Ru and Zr+Zr isobar collisions to precisely extract chemical potential differentials in the QCD phase diagram, thereby validating these collisions as a high-precision probe for four-dimensional QCD thermodynamics against lattice-QCD and Chiral Mean Field model predictions.
This paper outlines the LUXE experiment's use of high-intensity laser and electron beam collisions to probe non-perturbative strong-field QED phenomena like vacuum pair production, while also exploring how future colliders and beam-dump experiments can extend these studies to higher energy scales and search for new physics.
The paper proposes Vision Calorimeter (ViC), a novel framework that adapts visual object detectors with a physics-inspired heat-conduction operator to significantly improve the accuracy of anti-neutron position and momentum estimation in high-energy physics.
The paper proposes MORRIS, a novel tabletop experiment using a magnetically levitated sub-millimeter particle in a superconducting trap to search for non-Newtonian gravity via a Yukawa-like fifth force, with projected sensitivities that surpass existing bounds for screening lengths around 1 mm.
This paper proposes a supersymmetry model with R-parity violation to explain two rare 8 TeV four-jet events observed by the CMS Collaboration as a heavy down-squark decaying into two lighter first-generation right-handed squarks, while outlining the constraints and predictions for future LHC verification.
The paper introduces TIGER, a novel topology-agnostic hierarchical graph network that overcomes the limitations of single-topology models by leveraging the universal structure of sequential two-body decays to perform flexible, multi-task event reconstruction and classification for diverse physics processes at the LHC.
This paper presents a slim, quantized, and parameter-reduced version of the L-GATr jet tagger that achieves an order-of-magnitude reduction in energy cost with only a moderate performance decrease, paving the way for efficient trigger-level jet tagging at the LHC.
