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 details the successful design, simulation, manufacturing, and high-voltage testing of 1.5-meter-scale electrodes for dual-phase liquid xenon time projection chambers, which were subsequently installed as the anode and cathode in the upgraded XENONnT experiment.
This paper investigates the production of fully charmed tetraquarks in forward rapidity $pp$ collisions at LHC and FCC energies using the Color Glass Condensate formalism, revealing that the tensor state is predominantly produced via gluon-initiated processes while the axial-vector state is dominated by charm-initiated processes and is highly sensitive to intrinsic charm.
This paper evaluates the viability of , , and discrete flavour symmetries by incorporating the first JUNO measurement of into global neutrino oscillation data, revealing that the number of compatible mixing pattern cases is reduced from five to three for normal ordering and from four to two for inverted ordering at the confidence level.
This paper proposes analyzing heavy quark photoproduction associated with a leading neutron in proton-proton and proton-lead collisions at the LHC as a feasible method to probe the pion gluon distribution at small Bjorken- values, a kinematical range not previously covered by experiments.
This paper evaluates the design parameters for next-generation gaseous xenon time projection chambers targeting neutrinoless double-beta decay, finding that detectors using enriched Xe with optimized energy resolution and event reconstruction can achieve background rates below 0.2 events per tonne-year, though no single operating pressure is clearly optimal when balancing performance with construction feasibility.
This paper introduces a new parametrization for N-point energy correlators that enables the derivation of a general factorization theorem in the back-to-back limit and the analytic determination of leading non-perturbative power corrections for arbitrary N, including non-integer values, thereby facilitating future precision extractions of the strong coupling constant.
This paper proposes that existing ultra-clean underground NaI dark matter detectors can search for galactic axions produced by carbon-burning stars via resonant absorption of 440 keV axions, potentially probing axion-nucleon couplings in a parameter space that remains viable despite existing astrophysical constraints.
This paper introduces a novel algebraic modeling strategy for pion Generalized Parton Distributions that rigorously satisfies all QCD constraints, demonstrating through next-to-leading order calculations that gluons dominate the pion's response in deeply virtual Compton scattering at Electron Ion Collider kinematics.
This paper employs a Poincaré-covariant Dyson–Schwinger–Bethe–Salpeter framework to demonstrate that, despite the top quark's rapid weak decay, quantum chromodynamics predicts the existence of tightly correlated pseudoscalar and vector toponium bound states with masses near 345 GeV and minimal hyperfine splittings.
This study validates the reliability of a deconvolution-based algorithm for reconstructing photomultiplier tube waveforms across a large charge dynamic range (0–200 photoelectrons) and varying scintillation time profiles, demonstrating stable performance with approximately 1% charge non-linearity and the capability to handle muon-induced large signals.
