2131 papers

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.

Search for single production of a vector-like B' quark decaying to a top quark and a W boson in the single-lepton final state in proton-proton collisions at s\sqrt{s} = 13 TeV

The CMS collaboration presents a search for the single production of a vector-like B' quark decaying to a top quark and a W boson in proton-proton collisions at 13 TeV using 138 fb−1^{-1} of data, which sets the most stringent limits to date on the production of narrow-width singlet B' quarks with masses between 0.8 and 1.23 TeV.

HS3: A Descriptive, Interoperable Serialization Standard for Statistical Models in High-Energy Physics

This paper introduces HS3, a new implementation-agnostic, human-readable, and extensible serialization standard designed to provide a universal, FAIR-compliant format for representing and exchanging statistical models in high-energy physics, thereby overcoming the limitations of existing software-specific formats.

Semileptonic Decays of Λ→pℓ−νˉℓ\Lambda \to p \ell^{-} \bar{\nu}_{\ell} in the Light-Front Dynamics

This paper investigates the exclusive semileptonic decays of Λ→pℓ−νˉℓ\Lambda \to p \ell^{-} \bar{\nu}_{\ell} using a light-front quark model that incorporates nonvalence contributions, yielding branching ratios consistent with recent BESIII measurements and demonstrating the significant role of these nonvalence effects in such baryon decays.

Search for a leptoquark in events with a hadronically decaying τ\tau-lepton and missing transverse momentum using $pp$ collisions at s=13\sqrt{s}=13 TeV with the ATLAS detector

Using 140 fb−1^{-1} of 13 TeV proton-proton collision data collected by the ATLAS detector, this study searches for leptoquarks in final states containing a hadronically decaying τ\tau-lepton and missing transverse momentum, finding no excess over Standard Model predictions and setting 95% confidence level limits on couplings for U1U_1 vector-leptoquark masses between 1.5 and 3.0 TeV.

Development and integration of the NA64-DTC automation controller for the CERN "DESY Table'' motorized platform

This paper reports on the design, construction, and successful commissioning of the NA64-DTC, an ESP32-based remote automation controller that enables non-invasive, opto-isolated control of the CERN "DESY Table" motorized platform via HTTP, thereby facilitating remote operation and reducing manual intervention for various experiments.

Centrality dependence of charged-hadron pseudorapidity distributions in oxygen-oxygen collisions at sNN\sqrt{s_\mathrm{NN}} = 5.36 TeV

The CMS experiment reports the first measurement of charged-hadron pseudorapidity distributions in oxygen-oxygen collisions at sNN\sqrt{s_\mathrm{NN}} = 5.36 TeV, revealing that while the particle density per participating nucleon in central collisions matches that of lead-lead collisions, the data exhibit deviations from simple scaling laws that highlight the significant role of collision geometry and finite-size effects in light ion systems.

New Windows on Heavy Dark Matter: Mineral Melt Modelling and X-Ray Readout for Muscovite Mica

This paper proposes a novel framework for detecting heavy composite dark matter using muscovite mica as a paleodetector, combining Sedov-Taylor thermal spike modeling and SRIM/TRIM simulations with a new rapid X-ray fluorescence readout method to establish projected sensitivities and critique previous exclusion limits.

First Measurement of Correlated Charge Noise in Superconducting Qubits at an Underground Facility

This paper reports the first measurement of space- and time-correlated charge noise in superconducting qubits at an underground facility, demonstrating that while shielding and depth significantly reduce the rate of radiation-induced charge jumps compared to surface tests, the observed rate remains higher than expected from ambient gamma reduction alone, yet allows for over 22 hours of operation with zero correlated jumps at millimeter scales.
