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 introduces QUnfold, an open-source framework that reformulates the High-Energy Physics unfolding problem as a Quadratic Unconstrained Binary Optimization (QUBO) task, enabling competitive reconstruction accuracy through both classical solvers and quantum-compatible methods like D-Wave's hybrid solver.
This paper presents environmental measurements at the Sedrun Access Shaft in Switzerland, demonstrating that its low ground motion and electromagnetic background levels make it a viable site for an 800-meter atom interferometer designed to detect ultralight dark matter and gravitational waves.
Using a multi-channel joint analysis of BESIII data from collisions, this study identifies the exotic charmonium-like state as a resonance with significance, while extracting its pole positions and relative branching fractions across three decay channels.
This paper demonstrates a proof-of-concept where AI agents, directed by expert physicists, independently performed a complete precision measurement of the thrust distribution in LEP ALEPH data, marking a significant step toward integrating AI into the theory-experiment loop to accelerate discoveries in fundamental physics.
Using CMS Open Data from PbPb collisions at , this study presents preliminary measurements of the radial flow observable , confirming key collective phenomena such as long-range correlations and factorization that are consistent with ATLAS results at higher energies.
Using data samples of 99 million and 122 million mesons collected by the BABAR detector, this paper presents a search for the lepton flavour violating decays and , which are forbidden in the Standard Model but predicted by various new physics extensions.
This paper investigates the feasibility of measuring quantum entanglement and Bell-type spin-correlation observables in tau-lepton pairs produced at the proposed Super Tau-Charm Facility, demonstrating that high-statistical-significance resolution of these effects is achievable within the Standard Model framework using realistic detector conditions and integrated luminosities.
This paper presents the first systematic lattice QCD study of proton- scattering across multiple pion masses and lattice spacings, yielding scattering parameters and cross sections that agree with experimental data and confirm attractive interactions critical for nuclear theory and neutron star modeling.
This paper demonstrates that different, formally equivalent resummation prescriptions for the thrust distribution in annihilation yield non-negligible numerical differences that exceed standard theoretical uncertainties, thereby necessitating more conservative error estimates in strong coupling determinations.
This paper presents the first next-to-next-to-leading order (NNLO) QCD event generation for production matched to parton showers using the MiNNLOPS method, which incorporates a novel pointwise combination of soft and high-energy two-loop amplitude approximations to provide robust, publicly available predictions for Higgs-boson decay into photons with off-shell top-quark decays.
