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.
This paper presents a fast, data-driven parametric simulation tool for pixel sensors that bypasses the need for proprietary manufacturing details by using measurement inputs, demonstrating its efficiency and validation on the MALTA2 sensor to guide performance optimizations for the upcoming MALTA3 redesign.
This paper presents the development and validation of pre-supernova neutrino event generation capabilities within the sntools package, aiming to enable early warning detection and unified analysis of pre-collapse stellar neutrinos for current and next-generation detectors like Hyper-Kamiokande.
This paper presents a search for a Higgs boson decaying into soft unclustered energy patterns (SUEP) produced in association with a W or Z boson using 138 fb of 13 TeV proton-proton collision data, finding no significant excess over the Standard Model background and setting limits on the production cross section.
The XENONnT experiment reports a 3.3 measurement of coherent elastic neutrino-nucleus scattering from solar B neutrinos, which establishes a "neutrino fog" background that limits light dark matter detection sensitivity while also enabling constraints on the weak mixing angle and physics beyond the Standard Model.
Using the parton-hadron string dynamics (PHSD) transport model, this study predicts transverse momentum spectra and yield characteristics of identified particles in Au+Au collisions across various beam energies and centralities, highlighting the critical roles of baryon stopping and strangeness production while providing theoretical context for current and future heavy-ion beam energy scan programs.
This paper presents a reactor-based search for axion-like particles using a low-background CsI(Tl) detector, demonstrating the potential to probe previously unexplored parameter spaces for ALP masses between 1 keV and 10 MeV, including the cosmological triangle.
Using 2.01×10²¹ protons-on-target from the NuMI beam, the MicroBooNE experiment sets the world's strongest limits to date on the mixing angle of Higgs-portal scalar bosons in the 110–155 MeV mass range by searching for their decays into electron-positron pairs.
This colloquium reviews the past two decades of contributions from collider experiments (BABAR, Belle, BESIII, and CLEO-c) to the study of hadron production in open-charm meson pairs, aiming to deepen the understanding of quark confinement and nonstandard hadrons while outlining future prospects for the field.
Using Belle II data collected at SuperKEKB, this study searches for the ( = 0, 1, 2) processes near GeV and establishes 90% confidence level upper limits on their Born cross sections, finding them significantly smaller than those of related processes like .
This paper presents a comprehensive prediction of particle-induced backgrounds for the NUCLEUS experiment at the Chooz nuclear power plant, demonstrating through environmental measurements and Geant4 simulations that the setup achieves sufficient background rejection to enable the detection of Coherent Elastic Neutrino-Nucleus Scattering with a signal-to-background ratio greater than one in the sub-keV energy range.
