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 essay defends the Future Circular Collider (FCC) against climate-related criticisms by arguing that the project's scientific value and potential societal benefits outweigh its environmental costs, urging a shift from a mindset of renunciation to one of transformative innovation.
This paper proposes a hybrid neural density estimation method that combines flow-based reference distributions with classifier-estimated density ratios to create explicit, normalized target densities, enabling the construction of exact Asimov datasets and reducing Monte Carlo variance in simulation-based inference.
This paper presents comprehensive measurements of top-quark pair and single-top quark production cross sections using ATLAS detector data from LHC Run 2 (2015–2018), alongside recent results from 5 TeV operations and an initial analysis of Run 3 data at 13.6 TeV.
This paper computes the two-loop contributions to Higgs production via gluon-gluon fusion and decay into two photons arising from third-generation four-quark operators in the SMEFT, performed in the broken phase with full mass dependence to derive finite matching corrections, renormalization group effects, and new two-loop anomalous dimensions.
This paper proposes using highly sensitive quantum devices, such as superconducting qubits and trapped ions, to detect the faint electromagnetic signals from radiative decays of cosmic neutrinos and dark matter, demonstrating that current technology can probe dark matter candidates while future scalable architectures are needed to exceed limits on neutrino magnetic moments.
This paper presents the improvements and performance of dedicated triggers for beyond-the-standard-model long-lived particles in the CMS experiment, utilizing proton-proton collision data collected at 13.6 TeV during the 2022–2024 Run 3 period.
This review paper summarizes a decade of theoretical and experimental advances in muon physics, highlighting enhanced sensitivities in measuring muon properties and searching for new phenomena to probe physics beyond the Standard Model, including light new particles and hidden sectors, while discussing future opportunities for novel experimental concepts and facilities.
This paper presents the first next-to-leading order QCD predictions with parton-shower matching for the production and decay of scalars and heavy neutrinos in the Scotogenic model at 14 TeV and 100 TeV colliders, supported by the public release of the SM_Scoto FeynRules library and an analysis of future lepton collider prospects.
This paper investigates the interplay between low-energy flavor physics and dark matter phenomenology within the dimension-6 dark Standard Model Effective Field Theory, demonstrating that correlated multi-operator configurations are necessary to satisfy current constraints and defining tightly constrained benchmark regions for future collider searches.
Using a novel simulation-based inference framework to overcome computational and statistical challenges, this study performs a joint analysis of MiniBooNE and MicroBooNE data within a 3+1 sterile neutrino model, revealing a significant tension () between the two experiments that reduces the overall preference for sterile neutrinos to .
