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.
Using 140 fb of 13 TeV proton-proton collision data, the ATLAS experiment reports the first observation of triboson production with a significance of 5.9 standard deviations and derives constraints on anomalous quartic gauge-boson couplings within the effective field theory framework.
Using the CMS detector, this study presents the first measurements of correlations among mixed-order moments of two and three flow harmonics in XeXe and PbPb collisions, leveraging the distinct nuclear shapes of doubly-magic Pb and triaxially deformed Xe to probe initial-state geometry fluctuations and constrain the nonlinear hydrodynamic response of the quark-gluon plasma.
Using a four-dimensional amplitude analysis of proton-proton collision data from the LHCb experiment, this study confirms the existence of the exotic structure in decays and investigates its properties through both Flatté parametrization and triangle singularity mechanisms.
Using the full ATLAS Run 2 dataset at TeV, this paper presents the first measurement of the differential ratio between -channel single top-quark and antiquark production cross-sections, comparing these results to theoretical predictions and deriving constraints on the Wilson coefficient within an effective field theory framework.
This paper applies radiative corrections to recent MINERvA antineutrino-hydrogen scattering data to extract the nucleon axial-vector form factor and radius, thereby enabling more precise comparisons with lattice QCD predictions and reducing uncertainties in neutrino interaction modeling.
This paper presents training materials and resources developed by the HEP Software Foundation to equip physicists with Apptainer containerization skills, thereby enhancing the reproducibility, portability, and collaboration of High Energy and Nuclear Physics analyses.
This paper presents a fast, high-fidelity generative model based on score-driven diffusion and the Point-Edge Transformer architecture that successfully simulates realistic, high-multiplicity heavy-ion collision events through a two-stage training strategy, demonstrating its potential to replace computationally intensive traditional simulations.
This paper proposes a source-informed event selection strategy for neutrino telescopes that preferentially retains events aligned with known candidate sources, demonstrating that this approach can improve median point source sensitivity by factors of 2–3 with only modest computational overhead.
This paper evaluates solar neutrino flux fluctuations caused by solar gravity modes, concluding that while detecting individual modes via time-varying flux changes is currently impossible due to their small amplitude, the non-time-varying component could produce a measurable, activity-cycle-dependent net increase in the mean neutrino flux that offers a potential method for constraining g-mode excitation theories.
Using high-resolution XRISM/Resolve spectroscopy combined with NuSTAR data and plasma modeling, this study characterizes the plasma dynamics of the AM Herculis accretion column by resolving intrinsic Fe line broadening to reveal velocity and temperature gradients, confirming resonance anisotropy, and deriving a self-consistent shock temperature of 24.0 keV and density of cm to constrain the column's geometry.
