hep-ex papers | Gist.Science

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.

Probing $t$ -channel single top-quark and antiquark production via differential cross-section measurements at $\sqrt{s}=$ \SI{13}{\TeV} with the ATLAS detector

Using the full ATLAS Run 2 dataset at $\sqrt{s}=13$ TeV, this paper presents the first measurement of the differential ratio between $t$ -channel single top-quark and antiquark production cross-sections, comparing these results to theoretical predictions and deriving constraints on the Wilson coefficient $C^{3,1}_{Qq}$ within an effective field theory framework.

Nucleon axial-vector form factor and radius from radiatively-corrected antineutrino scattering data

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.

Solar Neutrino Flux Fluctuations Caused by Solar Gravity Modes

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.

Plasma Dynamics of Radiative Cooling Accretion Flow in AM Herculis with XRISM

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 $(5-6)\times10^{15}$ cm $^{-3}$ to constrain the column's geometry.

Towards foundation-style models for energy-frontier heterogeneous neutrino detectors via self-supervised pre-training

This paper proposes a self-supervised sparse ViT framework that leverages masked autoencoding and relational objectives to learn reusable representations from heterogeneous neutrino detector data, significantly improving reconstruction performance and data efficiency for energy-frontier experiments like FASERCal while demonstrating strong transferability across diverse detector technologies.

Measurement of Inclusive Charged-Current $\bar{\nu}_{\mu}$ Scattering on C, CH, Fe, and Pb at $\langle E_{\bar{\nu}}\rangle \sim$ 6 GeV with MINERvA

The MINERvA collaboration reports the first measurement of inclusive charged-current $\bar{\nu}_\mu$ cross sections on carbon, hydrocarbon, iron, and lead at a mean energy of $\sim 6$ GeV, revealing significant discrepancies between experimental data and current neutrino interaction models, particularly regarding nuclear effects at low antimuon transverse momentum.

QED radiative corrections in inverse beta decay from virtual pions

This paper evaluates pion-induced QED radiative corrections to the inverse beta decay cross section using heavy baryon chiral perturbation theory, demonstrating that these effects are small enough to enable sub-permille theoretical precision for antineutrino energies above 10 MeV.
