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 investigates the pair production of charged scalars () within the scotogenic model, demonstrating that the process is dominated by -channel exchange of singlet right-handed fermions (including the dark matter candidate) and providing predictions for future high-energy colliders to test the model's parameter space.
This paper presents a study analyzing representative heterogeneous applications from major High Energy Physics experiments to identify key characteristics that influence performance across various GPU portability layers, thereby guiding developers in selecting the most suitable technology for their specific needs.
This study explores the novel application of repurposed Water Cherenkov Detectors for high-resolution, non-invasive soil moisture monitoring in precision agriculture, demonstrating through experiments and simulations that this cosmic-ray-based approach offers a scalable and sensitive alternative to conventional methods for optimizing water use.
This paper utilizes recent LHCb and Belle II measurements of CP asymmetries in decays, combined with flavor-SU(3) relations and first-order breaking corrections, to generate new Standard Model predictions for CP violation and decay rates in related and processes.
This paper presents the integration of the invertible generative network CaloINN into the open-source interTwin Digital Twin Engine, utilizing post-processing modifications to enhance the accuracy of distribution tails in calorimeter shower simulations while maintaining computational efficiency.
This paper proposes a GeV-scale QCD axion model where the Peccei-Quinn symmetry is broken below the QCD scale and carried solely by the right-handed up quark, successfully evading standard constraints while predicting distinctive signatures such as heavy quark pair production at the LHC and rare Higgs or Z boson decays.
The BABAR collaboration presents preliminary results from a new blind analysis of 460 fb⁻¹ of data, confirming consistency with their 2009 measurement of the cross section to improve the precision of the muon anomalous magnetic moment prediction.
This paper presents recent BESIII results on pure leptonic and semileptonic decays of mesons and charm baryons, as well as baryon pair polarization, leveraging the world's largest datasets collected at open-charm production thresholds.
This paper reports new measurements of strong-phase differences in neutral meson decays using BESIII's large dataset near the threshold, alongside the first observation of correlated pairs above this threshold, which enables novel techniques for determining strong phases essential for CP violation studies.
This paper reviews recent LHCb and Belle II measurements of time-integrated CP asymmetries in hadron decays, highlighting progress in determining the CKM angle , the first observation of CP violation in baryon decays, and new studies of direct CP violation in mesons, while also discussing future prospects.
