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.

A study of multicavity concept applied to hexagonal coaxial haloscopes

This paper presents a study on scalable multicavity architectures for hexagonal coaxial haloscopes operating at 30 GHz, demonstrating that a triple-subcavity design with a novel rotational tuning mechanism achieves a threefold improvement in scanning rate over a single-cavity baseline while exploring the feasibility of further scaling to four subcavities within strict radial constraints.

Spin-flavor entanglement in Λb→ΛD\Lambda_b \to \Lambda D and weak phase extraction

This paper identifies a new spin-flavor entanglement structure in Λb→ΛD\Lambda_b \to \Lambda D decays that encodes weak phase information, establishing a quantitative relationship where the precision of extracting the CKM angle γ\gamma scales inversely with the Wootters concurrence of the entangled system.

Measurement of branching fractions of Ds+→KS0KS0π+π0D^+_s\to K^0_SK^0_S \pi^+\pi^0 and Ds+→KS0K+π0π0D^+_s\to K^0_S K^+\pi^0\pi^0

Using 7.33 fb−1^{-1} of e+e−e^+e^- collision data collected by the BESIII detector, this study reports the first observations of the hadronic decays Ds+→KS0KS0π+π0D^+_s\to K^0_SK^0_S\pi^+\pi^0 and Ds+→KS0K+π0π0D^+_s\to K^0_S K^+\pi^0\pi^0 and determines their branching fractions to be (4.08±0.46stat±0.45syst)×10−3(4.08\pm0.46_{\rm stat}\pm0.45_{\rm syst})\times 10^{-3} and (3.32±0.64stat±0.31syst)×10−3(3.32\pm0.64_{\rm stat}\pm0.31_{\rm syst})\times 10^{-3}, respectively.

Dissecting Jet-Tagger Through Mechanistic Interpretability

This paper applies mechanistic interpretability techniques to a Particle Transformer for top quark tagging, revealing that a sparse six-head circuit effectively replicates the full model's performance by utilizing an energy correlator-based representation to identify 2-prong substructure, thereby demonstrating that gradient descent can rediscover physically meaningful features in jet physics without supervision.

Weibel-mediated filamentary structures observed in the ICF context

This paper demonstrates through theoretical and particle-in-cell modeling that transverse ballistic cooling in expanding laser-irradiated plasma plumes drives Weibel-mediated electron current filaments, successfully explaining magnetic fluctuation data from OMEGA and Laser Megajoule experiments.
