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.

Design and Development of Portable RPC-Based Cosmic Muon Tracker

This paper presents the design, development, characterization, and applications of a portable Cosmic Muon Tracker (CMT), a stack of eight one-square-foot Resistive Plate Chambers (RPCs) derived from the India-based Neutrino Observatory's large-scale detector technology, intended for small-scale particle physics experiments and student training.

Comparing effective temperatures in standard and Tsallis distributions from transverse momentum spectra in small collision systems

This study investigates transverse momentum spectra of light charged hadrons in RHIC d+Au and p+p collisions at sNN=200\sqrt{s_{NN}}=200 GeV, revealing that effective temperatures derived from standard and Tsallis distributions exhibit systematic decreases across distribution types and collision centralities, while maintaining perfect linear relationships between them.

Finding BSM Needles in Electromagnetic Haystacks at DUNE

This paper presents a detailed background mitigation analysis for the DUNE near detector, evaluating its capability to constrain or discover long-lived beyond-Standard-Model particles by investigating hard electromagnetic signatures in e+ee^+e^-, eγe^-\gamma, γ\gamma, and γγ\gamma\gamma final states while accounting for realistic neutrino-induced backgrounds and detector effects.

Chasing the two-Higgs-doublet model via electroweak corrections at e+ee^+e^- colliders

This paper demonstrates that precision measurements of Higgs boson production with neutrino pairs at future e+ee^+e^- colliders, incorporating next-to-leading-order electroweak corrections, can reveal two-Higgs-doublet model effects even in the Higgs alignment limit.

Cryogenics and purification systems of the ICARUS T600 detector installation at Fermilab

This paper details the design, reconstruction, and commissioning of the cryogenic and purification systems for the ICARUS T600 detector, which was relocated from Gran Sasso to Fermilab and upgraded for operation with high-intensity neutrino beams to search for sterile neutrinos and measure neutrino-argon cross sections.

Experimental study of the reaction Ξ0nΛΛXΞ^{0}n\rightarrowΛΛX using Ξ0Ξ^{0}-nucleus scattering

Using a large sample of J/ψJ/\psi events collected by the BESIII detector, researchers observed the reaction Ξ0nΛΛX\Xi^0 n \rightarrow \Lambda\Lambda X with a statistical significance of 6.4σ\sigma and measured its cross section, while finding no evidence for an HH-dibaryon in the ΛΛ\Lambda\Lambda final state.

Binned and Unbinned Transverse Single Spin Asymmetry Extraction, including Background Subtraction and Unfolding

This paper presents general methods for extracting transverse single-spin asymmetries using both binned and unbinned maximum likelihood approaches, specifically designed to address experimental challenges such as time-varying polarization, unequal spin-state luminosities, and the need for background subtraction and kinematic unfolding.
