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 a novel high-luminosity experimental approach using tagged hyperons produced in proton-proton collisions within a nested-target setup to precisely measure hyperon-nucleon interactions, thereby addressing the uncertainties in the equation of state that underlie the hyperon puzzle in neutron stars.
This paper presents a systematic study of semi-leptonic Higgs decays to electroweak gauge bosons at NLO QCD and electroweak accuracy, demonstrating that while finite fermion masses and higher-order corrections significantly modify angular observables, the process retains an effective two-qutrit description suitable for quantum tomography and entanglement analysis.
The FASER experiment presents its latest physics results from LHC Run 3, featuring world-leading dark photon exclusion limits, the first observation of electron neutrinos, and pioneering measurements of neutrino cross sections and charm hadron production using both emulsion and electronic detectors.
This paper demonstrates that energetic final-state radiation induces decoherence and significantly reduces the entanglement of fermion-antifermion pairs produced at colliders, with statistically significant experimental signals predicted for current datasets from production at the LHC and production at Belle 2.
This paper presents the development and validation of a scalable, multi-channel FPGA-based data acquisition system featuring NINO ASIC front-end electronics and a 500MHz sampling rate, which successfully demonstrates accurate two-dimensional muon position tracking for non-destructive muon scattering tomography applications.
This study utilizes the PHQMD approach with a novel momentum-dependent potential to demonstrate that a soft, momentum-dependent nuclear equation of state best reproduces experimental flow data for protons and light clusters in intermediate-energy heavy-ion collisions, while also revealing distinct flow signatures that can help discriminate between different cluster formation mechanisms.
This paper proposes a method to probe new physics in decays by analyzing the angular distribution of the full cascade , demonstrating through simulated data that this approach can constrain right-handed and tensor current couplings with approximately 5–6% precision while incorporating recent lattice QCD form factor correlations.
This paper analyzes recent NOA and T2K data to test the non-unitary mixing hypothesis, providing updated best-fit parameters and tighter constraints on unitary violation while demonstrating that non-standard parameters can alleviate tensions between the experiments, alongside a projection of future sensitivities for NOA, T2K, and DUNE.
This paper demonstrates that detecting tau neutrinos at the DUNE far detector significantly enhances sensitivity to Non-Standard Interactions, particularly the parameter, while also improving constraints on mass hierarchy, CP violation, mixing octants, and the unitarity of the PMNS matrix.
This paper demonstrates that enriching the NuGraph2 architecture with physics-inspired, context-aware input features significantly improves semantic segmentation for underrepresented particles like Michel electrons in Liquid Argon Time Projection Chambers, outperforming auxiliary decoders and energy-based regularization due to the model's current hit-level limitations.
