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.
The paper introduces GollumFit, an open-source framework designed to efficiently perform binned-likelihood analyses on IceCube neutrino telescope data by incorporating both general and specific model parameters to handle complex fitting scenarios with numerous nuisance parameters.
This paper utilizes the relativistic Boltzmann transport equation within the relaxation time approximation to predict and estimate, for the first time, the emergence of magneto-Thomson and transverse Thomson effects in a hot and dense hadronic medium under external magnetic fields, thereby revealing new higher-order thermoelectric transport phenomena relevant to relativistic heavy-ion collisions.
This paper provides practical recommendations and considerations from researchers across major particle physics experiments on adopting emerging machine learning-based unbinned unfolding techniques to replace traditional binned histogram methods for more flexible, high-dimensional data analysis.
This paper presents a next-to-leading order QCD calculation of diboson production with leptonic decays and definite polarization states within the SMEFT framework, matched to parton showers to enable precise polarization-template and quantum-tomography analyses at the LHC.
This paper presents the design and characterization of a dual-readout photosensor system using Hamamatsu R8520-406 PMTs that successfully mitigates cosmic muon saturation to enable the RELICS experiment to detect coherent elastic neutrino-nucleus scattering signals at the surface level.
This study utilizes beam-spin asymmetry measurements from the KaonLT experiment at Jefferson Lab to demonstrate that the ratio remains flat with respect to and is better described by Regge models than by generalized parton distribution formalism, indicating that the hard/soft factorization regime has not yet been reached in exclusive pion electroproduction at the explored kinematics.
This paper presents a precise, model-independent dispersive determination of resonance pole parameters for various mesons up to 2.02 GeV by analytically continuing forward dispersion relations and global fits to scattering data, confirming established resonances below 1.7 GeV while identifying additional poles above this threshold and illustrating that resonances do not always trace full circles in Argand diagrams.
This paper presents a fully differential next-to-next-to-leading order QED calculation of the process, implemented in the McMule framework to enable precise luminosity measurements for electron-positron colliders with center-of-mass energies up to a few GeV.
The DAMSA conceptual design white paper proposes a novel short-baseline accelerator experiment utilizing the PIP-II LINAC to probe MeV-to-sub-GeV dark-sector messengers and rare Standard Model signals by overcoming beam-dump sensitivity limits with a compact detector, a strategy whose feasibility will be validated through the proposed Little DAMSA Path-Finder (LDPF) proof-of-concept experiment.
Using 366.4 days of data from the LUX-ZEPLIN detector, researchers measured the cosmic-ray muon flux at the Sanford Underground Research Facility's Davis Cavern to be , providing critical background information for dark matter and rare decay searches.
