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 demonstrates that upcoming low-threshold coherent elastic neutrino-nucleus scattering experiments at major spallation sources (ESS, J-PARC, and CSNS) will significantly probe previously unexplored parameter space for sub-GeV thermal dark matter produced via neutral pion decays and mediated by vector portals.
This paper reframes Quantum Neural Network design from state reachability to learnability by introducing geometric design principles and the almost Complete Local Selectivity (aCLS) criterion, demonstrating that architectures requiring joint dependence on data and trainable weights enable adaptive feature learning and outperform traditional schemes with greater efficiency.
This paper demonstrates a quantum-enhanced dark matter search technique using a superconducting qubit to prepare a microwave cavity in a non-classical Fock state, which stimulates signal photon emission to increase the scan rate by a factor of 2.78 and excludes kinetic mixing angles for dark photons around 5.965 GHz.
This paper proposes that relic neutrinos from the Big Bang can be detected via parametric fluorescence, a coherent scattering process in atomic or molecular systems where a massive neutrino decays into a lighter neutrino and a signal photon, offering a promising detection method with event rates potentially reaching one per year in optimized target volumes.
This paper demonstrates that uncertainties in final-state interaction modeling can distort reconstructed neutrino-energy spectra in next-generation long-baseline experiments like DUNE to an extent comparable to or exceeding oscillation parameter variations, thereby creating potential degeneracies that necessitate improved theoretical characterizations and dedicated experimental measurements for robust results.
This paper introduces NuBench, an open benchmark comprising seven large-scale simulated datasets across six detector geometries, designed to facilitate the development and comparative evaluation of deep learning-based event reconstruction methods for neutrino telescopes.
This paper introduces MEDIC, a simulation-driven neural network framework that leverages machine learning to automate anomaly detection and localize faulty components in particle physics detectors, serving as a foundational step toward advanced data quality monitoring systems for future collider experiments.
This paper investigates a string closepacking mechanism during hadronization that increases effective string tension to explain the LHC-observed rise in strange-hadron production with multiplicity, a model that successfully tunes to data and qualitatively describes many particle ratios despite challenges with the non-strange p/pi ratio and specific spectral shapes.
This paper presents the precise measurement of muon fluxes in the forward pseudorapidity region of the SND@LHC experiment using 2023–2025 proton and heavy-ion collision data, reporting values that agree with Monte Carlo predictions and are dominated by systematic uncertainties.
This paper demonstrates that reconstructing spin density matrices via quantum tomography and analyzing quantum information-inspired observables for near-threshold top-antitop production at the LHC significantly enhances the sensitivity to detect subtle toponium formation effects.
