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.

Non-parametric and continuous extraction of amplitudes in realistic electroweak penguin decays

This paper demonstrates that a novel, model-independent method for extracting continuous decay amplitudes in $B\to V(\to M_1M_2)\ell^+\ell^-$ processes remains robust and effective when applied to realistic experimental data containing non-factorising detection efficiencies and backgrounds, thereby enabling broader kinematic studies and improved sensitivity to new physics.

New Physics in $b \to s \tau^+\tau^-$ Processes and Correlations with $R(D^{()})$ and $B\to K^{()}\nu\bar\nu$ : An (SM)EFT Analysis

Motivated by anomalies in $R(D^{(*)})$ and $B\to K^{(*)}\nu\bar\nu$ , this paper presents an SMEFT analysis predicting that New Physics could enhance $b\to s\tau^+\tau^-$ branching ratios by several orders of magnitude, making them accessible to future LHCb, CMS, and Belle II experiments while providing a crucial method to distinguish between different New Physics scenarios.

Interpreting the High-Recoil LUX-ZEPLIN Event with Bino-/Singlino-like and Higgsino Dark Matter

This paper interprets a recent high-recoil nuclear event observed by the LUX-ZEPLIN experiment through two supersymmetric scenarios: an elastic scattering model involving a bino- or singlino-like neutralino with specific Higgsino asymmetry, and an inelastic scattering model featuring a pseudo-Dirac Higgsino, both of which predict distinct recoil spectra that can be distinguished from the candidate signal.

First double-differential cross-section measurements in proton multiplicity and kinematics for mesonless $\nu_{\mu}$ charged-current interactions on argon using the MicroBooNE detector

Using the full MicroBooNE dataset, this paper presents the first double-differential cross-section measurements for mesonless $\nu_{\mu}$ charged-current interactions on argon as a function of proton multiplicity and kinematics, revealing significant discrepancies between the data and current event generator predictions that highlight deficiencies in modeling final-state interactions.

Lagrangian-based model of the $e^+e^- \to V \bar V$ process applied to the $e^+e^- \to D^{\ast+} D^{\ast-}$ data

This paper derives a Lagrangian-based Breit-Wigner formula for the $e^+e^- \to V\bar{V}$ process and validates its parameters by fitting 2022 BESIII experimental data on $e^+e^- \to D^{\ast+}D^{\ast-}$ production.

WLCG Mini-Capability Challenge: Host Tuning to Im- prove WAN Data Transfers

This paper presents the results of a WLCG mini-capability challenge demonstrating that while host-level tuning can significantly improve WAN data transfer speeds at sites with capable storage and network infrastructure, its effectiveness is strictly limited by local bottlenecks such as storage I/O or NIC capacity, and the process also serves as a valuable diagnostic tool for identifying configuration issues.
