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 an analysis of over two tonne-years of CUORE data demonstrating that optimized selection techniques enable the experiment to effectively explore the keV-scale energy region with improved resolution and reduced background, thereby validating tonne-scale cryogenic calorimeters as versatile tools for rare event and dark matter physics across a wide energy range.
This paper presents an updated version of the TGlauberMC Monte Carlo code (v3.3) with improved nuclear density profiles and nucleon substructure treatments to provide precise predictions for initial-state observables and centrality-dependent multiplicity in upcoming oxygen-oxygen, neon-neon, and proton-oxygen collisions at the LHC.
These lecture notes provide a graduate-level introduction to the strong CP problem and QCD axion physics from an effective field theory perspective, covering the construction of chiral EFT, the derivation of CP-odd observables, generalizations to various gauge theories, critiques of alternative solutions, and the standard Peccei-Quinn mechanism.
This paper presents a robust modeling framework that couples pulsed-power electrical circuit simulations with one-dimensional hydrodynamic codes to accurately design and optimize experiments for generating expanded warm dense matter in thin metallic foils confined within sapphire cells.
This closeout report for LDRD 23-050 details the physics case and conceptual design for a second, complementary Electron-Ion Collider (EIC) detector, outlining its scientific potential, innovative technology requirements, and strategic role in maximizing the EIC's multi-decade research capabilities.
This paper demonstrates that the High Luminosity LHC has sufficient sensitivity to exclude the remaining allowed parameter space of a generic Two Higgs Doublet Model with right-handed neutrino couplings, which was proposed to explain the observed anomalies via a charged Higgs boson.
This paper presents recent inclusive and differential measurements of top quark production in association with photons by the ATLAS and CMS collaborations, utilizing LHC data to test Standard Model predictions and probe potential modifications to top-photon couplings via effective field theory.
The ATLAS collaboration reports inclusive cross-section measurements for single-top and production at various LHC center-of-mass energies, along with derived observables like and nuclear modification factors, all of which show good agreement with Standard Model predictions.
The ATLAS collaboration measured the -channel single top-quark production cross sections in proton-proton collisions at TeV, obtaining precise values for top-quark and top-antiquark rates that were subsequently used to set limits on EFT operators and CKM matrix elements.
Using 140 fb of 13 TeV proton-proton collision data from the ATLAS detector, this study searches for flavour-changing neutral current interactions between the top quark and the Higgs boson in multilepton final states, setting observed upper limits on the branching ratios of and at and , respectively.
