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 study establishes a low-energy ion injection scheme into a gaseous detector and measures the ionization yield of fluorine ions in low-pressure gas, finding a value of 0.45 at 30 keV to improve the accuracy of direction-sensitive dark matter search experiments.
This paper benchmarks quantization techniques and the Google Coral Edge TPU for neutrino interaction recognition, demonstrating that while the Edge TPU offers significantly lower energy consumption than CPUs and GPUs with minimal accuracy loss (particularly for Inception V3), it operates at speeds comparable to CPUs but an order of magnitude slower than GPUs.
This paper proposes that quarkonium suppression in heavy-ion collisions is caused by a dynamical Hawking-Unruh causal horizon formed during initial fragmentation, which instantly decouples heavy quark pairs when their bound-state radius exceeds the horizon, thereby explaining the observed suppression hierarchy and the vanishing elliptic flow without requiring thermalized medium interactions.
This paper proposes GravNet, a conceptual design for a global network of geographically separated detectors operating in strong magnetic fields to search for high-frequency gravitational waves (MHz to GHz) by synchronizing measurements to distinguish signals from noise and enhance detection significance.
This paper proposes a novel cogenesis framework based on the type-I Dirac seesaw mechanism, where the out-of-equilibrium decays of heavy vector-like fermions simultaneously generate the baryon asymmetry and an asymmetric dark matter component, allowing for successful cogenesis with dark matter masses ranging from 100 MeV to 39 TeV while remaining testable through neutrino, dark matter, CMB, and gravitational wave observations.
This paper introduces PySiPMGUI, an open-source, platform-independent Python-based graphical user interface that automates the characterization of Silicon Photomultipliers (SiPMs) using PyVISA-controlled instruments to support quality assurance in diverse high-energy and astroparticle physics experiments.
This paper reviews recent LHC results, highlighting the discovery of the odderon, evidence for gluon saturation in heavy-ion collisions, and the potential for detecting axion-like particles through photon-induced processes.
This paper demonstrates that while molecular and molecule-compact admixture models for the tetraquark produce similar invariant-mass line shapes, their distinct - femtoscopic correlation functions offer a sensitive and complementary method to distinguish between these structural scenarios in future LHC measurements.
Using QCD Laplace Sum Rules with next-to-leading order perturbative corrections and dimension-six non-perturbative condensates, this study predicts a light tensor hybrid meson mass of approximately 2038 MeV, suggesting that the and/or resonances may contain a significant hybrid component, while also providing the first NLO calculation of the tensor hybrid topological charge.
This paper presents the development and characterization of a prototype one-dimensional position-sensitive detector using a NaI(Tl) scintillator read out by SiPM arrays at both ends, designed to enhance the energy resolution, position sensitivity, and background rejection of hard X-ray Compton polarimeters like CXPOL.
