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.
The paper advocates for a bold, long-term shift in particle physics research toward the development of a yotta-eV scale tau-lepton collider located in the Oort cloud, arguing that despite requiring Kardashev Level-I or II civilization capabilities, this approach should become the community's primary focus for precision Higgs studies and new particle discovery.
This paper investigates the photoproduction and nuclear absorption of charmonium on C and W targets near the kinematic threshold using a collision model with nuclear spectral functions, demonstrating that calculated observables are sensitive to absorption scenarios and could help determine the -nucleus cross section for future experiments at the CEBAF facility.
This paper establishes an analytical connection between triaxial nuclear shapes and three-particle correlations in relativistic heavy-ion collisions, demonstrating that specific flow and momentum fluctuation observables are directly proportional to the nuclear triaxiality parameter .
This paper presents a first sensitivity study demonstrating that a simultaneous joint fit of LHCb and Belle II data for decays, utilizing event-by-event reweighting to handle non-SM biases and shared form-factor parameters, significantly reduces model-induced biases and improves constraints on New Physics Wilson coefficients compared to independent analyses.
This paper investigates charged current induced electron-proton scattering at JLab and MAMI by calculating various cross sections and polarization observables with and without time-reversal invariance, aiming to provide alternative constraints on the axial vector form factor to benefit neutrino oscillation experiments.
This paper investigates a directional geoneutrino detection method using a Cherenkov liquid scintillator to identify Potassium-40 neutrinos and image the Earth's large-scale internal structures, demonstrating that an exposure of 2.8 kiloton-years is sufficient for a 3-sigma discovery of potassium neutrinos and 10.6 kiloton-years to reject a uniform geoneutrino distribution.
This paper presents a comprehensive, web-enabled data acquisition system based on the MIDAS framework for gaseous detectors, which has been successfully deployed and validated in the PandaX-III experiment to support real-time monitoring and a unified workflow from data acquisition to offline analysis.
This paper presents a sensitivity study using the BESIII experiment to propose a model-independent method for determining the branching fraction of decays into three-body final states by simultaneously analyzing four specific semileptonic -meson decay channels.
This paper outlines the preliminary, site-specific installation plans and logistical challenges for the complex ILD and SiD detectors at the International Linear Collider, emphasizing that these strategies remain provisional pending the project's final approval and interaction point selection.
This paper presents a self-contained treatment of Blobel's Regularized Unfolding (BRU), a method that models true distributions using cubic B-splines and employs eigenmode decomposition for automatic regularization strength determination, offering a distinct alternative to conventional histogram-based approaches like Tikhonov regularization and Richardson-Lucy iteration.
