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 ALICE measurements of W and Z boson production cross sections in pp collisions at TeV via their electronic decay channels, comparing the results with perturbative QCD calculations and reporting the first LHC observation of W production and associated hadrons as a function of charged-particle multiplicity.
This paper presents the first complete NNLO QCD calculation for hadron production in deep-inelastic scattering at finite transverse momentum, utilizing a novel -subtraction framework to resolve infrared divergences and significantly improve theoretical precision for interpreting high-precision experimental data and future Electron-Ion Collider studies.
This study utilizes the GiBUU framework to demonstrate that while pion final-state interactions have a moderate impact on proton decay search sensitivity in water Cherenkov detectors, the choice of Fermi momentum distribution constitutes the dominant systematic uncertainty affecting atmospheric neutrino background estimates.
This paper presents a fast, data-driven simulation method for the MALTA2 depleted monolithic active pixel sensor that accurately reproduces measured in-pixel efficiency without requiring proprietary process details, offering a computationally efficient alternative to TCAD simulations for optimizing future high-rate particle tracking and calorimetry designs.
This paper presents a latency-optimized, hierarchical sparsity compression pipeline implemented in Chisel for FPGAs, which rearranges sparse sensor data from multiple FIFO interfaces to fewer streams to enable efficient Graph Neural Network acceleration in high-throughput, low-latency first-level triggers for collider experiments like Belle II.
This paper utilizes experimental data, lattice QCD calculations, and Roy equation-based dispersive representations to compute the subthreshold parameters of scattering, employing Monte Carlo sampling to quantify uncertainties and analyzing the impact of theoretical correlations between scattering lengths.
This paper presents a model-agnostic tracking algorithm capable of reconstructing a broad class of smooth, non-helical particle trajectories without prior specification, thereby enabling the discovery of unexpected physics signatures that standard helix-based algorithms miss.
Using combined Belle and Belle II data, this study presents the first observation of the decay , provides evidence for , and sets an upper limit for , thereby determining their absolute branching fractions and advancing the understanding of singly Cabibbo-suppressed charm baryon decay mechanisms.
This paper presents an exploratory study demonstrating how a proposed second interaction region at the Electron-Ion Collider, featuring enhanced forward acceptance, would enable the detection of intact light nuclei to map their spatial parton distributions through coherent diffractive processes.
This paper presents a global determination of parton distribution functions that incorporates higher twist corrections for deep-inelastic scattering and linear power corrections for LHC jet data using a theory covariance formalism, demonstrating improved data description and perturbative convergence for key phenomenological observables like Higgs production and determination.
