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 proposes using high-energy photons that convert into electron-positron pairs within the Belle-II detector at lepton colliders to measure quantum information observables, demonstrating that single and double conversion processes can significantly probe phenomena such as Bell inequality violations, quantum discord, and steerability in GeV-scale diphoton systems.
This paper presents a renormalon-subtracted potential nonrelativistic QCD framework that combines variational and Green's function Monte Carlo methods with NNLO potentials to predict the masses of fully-heavy baryons and the binding properties of fully-heavy tetraquarks, achieving improved perturbative stability while identifying discrepancies with lattice QCD that are consistent with neglected corrections.
This paper calculates tensor-polarized parton distribution functions for the deuteron using a convolution model, revealing significant discrepancies with existing HERMES data that suggest the need for new theoretical mechanisms beyond a simple proton-neutron bound system, while providing predictions for upcoming experimental tests at Jefferson Lab and Fermilab.
This paper demonstrates that charged-current neutrino interactions on argon at facilities like DUNE and SBND can constrain in-medium hyperon potentials through final-state interaction observables, thereby providing critical inputs to resolve the hyperon puzzle in neutron star equations of state.
This paper demonstrates that quarkyonic matter, when dressed with in-medium hyperon potentials constrained by hypernuclear and neutrino data, statistically resolves the neutron-star hyperon puzzle by delaying the onset of charged hyperons and suppressing core strangeness, thereby allowing for hyperon-free stars while predicting a significantly reduced sensitivity of the maximum mass to hyperon potentials compared to mean-field models.
This paper investigates how the running of the QCD coupling affects anti-collinear resummation in JIMWLK evolution, deriving a resummed BFKL kernel that reveals a significant reduction in the Pomeron intercept due to combined resummation and coupling effects, despite a surprising cancellation that leaves the characteristic function at unchanged.
This paper reports on the successful commissioning and operation of the fully integrated, low-latency (1.053 µs) Graph Neural Network Electromagnetic Calorimeter Trigger Module at the Belle II experiment, which utilizes hardware-algorithm co-design and online monitoring to achieve bit-accurate performance compatible with the system's first-level trigger requirements.
Using approximately 1.3 kg-day of data from the DAMIC-M prototype detector, this study establishes competitive 90% confidence level upper limits on the dark matter-electron scattering cross section for sub-MeV solar-reflected dark matter, effectively probing a mass regime inaccessible to standard halo searches.
Using QCD sum rules, this paper predicts the mass and decay width of the fully-beauty tensor tetraquark , concluding that while it is stable against strong decays into heavy meson pairs, it transforms into conventional particles via annihilation with a calculated width of MeV.
This report summarizes the 7th ALEGRO workshop held in March 2026, which brought together the international community to review progress in advanced wakefield accelerators, discuss the design of a future 10 TeV linear collider, and explore applications ranging from high-energy physics to free-electron lasers and AI-driven accelerator control.
