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 derives terrestrial constraints on Majorana bulk neutrinos within the Dark Dimension scenario by analyzing their mass spectrum and mixing, demonstrating that KATRIN beta-decay data provides the strongest limits on Yukawa couplings while the Kaluza-Klein tower effectively screens neutrinoless double beta decay signals.
The NOvA Test Beam experiment utilized a 30-ton liquid scintillator detector at Fermilab from 2019 to 2022 to analyze tagged particles and refine the understanding of systematic uncertainties related to detector response, energy calibration, and resolution, thereby improving the precision of the NOvA neutrino oscillation measurements.
This paper proposes a generalized chiral model featuring inelastic scalar dark matter to explain the 248 keV nuclear recoil event observed by the LZ collaboration, where a small mass splitting between nearly degenerate states suppresses low-velocity scattering while enhancing high-energy interactions consistent with current experimental constraints and relic abundance.
This paper demonstrates that enforcing -channel unitarity in high-energy elastic $pp$ scattering models significantly increases the extracted dynamical gluon mass scale from approximately 300–420 MeV to 750–1100 MeV, revealing that the physical infrared scale is a unitarity-dressed quantity determined jointly by the nonperturbative gluon propagator and multiple-exchange dynamics.
This paper presents a comprehensive lattice QCD study using RBC/UKQCD ensembles to determine the masses, decay constants, and compositeness parameters of positive- and negative-parity charm-strange and bottom-strange mesons, providing the first lattice results for and and confirming that the positive-parity states are predominantly molecular in nature.
This paper introduces a qubit-qutrit quantum tomography technique to certify entanglement in and systems despite incomplete density matrix data, thereby providing a novel probe of nonperturbative QCD hadronization and spin evolution.
This paper introduces a method and open-source software tool called Combiner that applies the Best Linear Unbiased Estimator (BLUE) approach to simultaneously combine measurements of physics parameters and their associated systematic uncertainties, demonstrating that this joint approach improves precision and provides more reliable uncertainty estimates compared to previous approximate methods.
This paper demonstrates through Monte Carlo simulations that a Bayesian criterion employing a Jeffreys prior outperforms the classical frequentist Li-Ma approach in On/Off analysis by achieving lower Type I and Type II error rates and offering greater robustness against overdispersed background distributions.
This paper demonstrates that a model-independent angular analysis of decays can distinguish between massless and massive invisible fermions while simultaneously discriminating among various interaction types and chiral structures.
This paper proposes a differentiable and Bayesian optimization framework for automatically determining optimal bin boundaries in multi-dimensional discriminants using Gaussian Mixture Models, demonstrating superior signal sensitivity compared to traditional hand-crafted or one-dimensional binning strategies in high-energy physics analyses.
