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 presents the detector configuration, calibration methods, and performance characterization of the LiFE-SNS experiment, which utilizes tritium-embedded LiF crystals and magnetic microcalorimeters to achieve precision measurements of the tritium spectrum for the search of keV-scale sterile neutrinos.
This paper proposes a fully data-driven, weakly supervised bidirectional conditional diffusion network that iteratively simulates and reconstructs photomultiplier tube waveforms to accurately resolve overlapping photoelectrons without requiring ground-truth labels.
This paper introduces MoreFit, a high-performance framework for unbinned maximum likelihood parameter estimation in particle physics that leverages just-in-time compiled computation graphs, novel automatic optimizations, and heterogeneous backends (OpenCL and LLVM/Clang) to achieve superior speed and efficiency across diverse hardware platforms.
This paper systematically evaluates the sensitivity of four semi-supervised anomaly detection methods to untunable hyperparameters in the search for Beyond the Standard Model physics and proposes a robust, non-parametric permutation test for statistical assessment.
This paper presents an analysis of over two tonne-years of CUORE data demonstrating that optimized selection techniques enable the experiment to effectively explore the keV-scale energy region with improved resolution and reduced background, thereby validating tonne-scale cryogenic calorimeters as versatile tools for rare event and dark matter physics across a wide energy range.
This paper presents an updated version of the TGlauberMC Monte Carlo code (v3.3) with improved nuclear density profiles and nucleon substructure treatments to provide precise predictions for initial-state observables and centrality-dependent multiplicity in upcoming oxygen-oxygen, neon-neon, and proton-oxygen collisions at the LHC.
These lecture notes provide a graduate-level introduction to the strong CP problem and QCD axion physics from an effective field theory perspective, covering the construction of chiral EFT, the derivation of CP-odd observables, generalizations to various gauge theories, critiques of alternative solutions, and the standard Peccei-Quinn mechanism.
This paper derives model-independent expansions to quantify leading corrections to the smoothness and on-shell approximations in femtoscopy and coalescence, demonstrating that while these corrections are generally small (at or below the percent level) for LHC energy collisions, they can be efficiently evaluated with the same numerical complexity as standard methods.
This paper presents a robust modeling framework that couples pulsed-power electrical circuit simulations with one-dimensional hydrodynamic codes to accurately design and optimize experiments for generating expanded warm dense matter in thin metallic foils confined within sapphire cells.
This closeout report for LDRD 23-050 details the physics case and conceptual design for a second, complementary Electron-Ion Collider (EIC) detector, outlining its scientific potential, innovative technology requirements, and strategic role in maximizing the EIC's multi-decade research capabilities.
