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.
The ALICE collaboration at the LHC reports the first measurement of the transverse-momentum differential production cross section of B mesons in proton-proton collisions at TeV down to , finding results consistent with perturbative quantum-chromodynamics models.
This paper demonstrates that the choice of prescription in the Collins-Soper-Sterman framework introduces a significant intrinsic theoretical uncertainty in Transverse Momentum Dependent distribution extractions, yielding consistent results for low-energy data but causing substantial discrepancies in intermediate-to-high energy predictions.
This study employs QCD light-cone sum rules to calculate the magnetic dipole moments of hidden-charm pentaquarks using four distinct diquark-diquark-antiquark interpolating currents, demonstrating that these electromagnetic observables are highly sensitive to internal quark configurations and can effectively discriminate between compact and molecular structural models.
This paper demonstrates that simulation-based inference methods, particularly optimal-observable estimators and robust likelihood-ratio approaches, offer superior or comparable sensitivity to anomalous couplings in the channel compared to traditional histogram analyses, highlighting their potential to surpass current LHC constraints with Run 3 data.
This paper evaluates the viability of , , and discrete flavour symmetries by incorporating the first JUNO measurement of into global neutrino oscillation data, revealing that the number of compatible mixing pattern cases is reduced from five to three for normal ordering and from four to two for inverted ordering at the confidence level.
This paper introduces a new parametrization for N-point energy correlators that enables the derivation of a general factorization theorem in the back-to-back limit and the analytic determination of leading non-perturbative power corrections for arbitrary N, including non-integer values, thereby facilitating future precision extractions of the strong coupling constant.
This paper enhances the explainability of quark-gluon jet taggers by identifying key latent features, evaluating the limitations of Shapley values in correlated inputs, and employing symbolic regression to derive compact formulas that approximate the tagger's output.
This paper presents a prediction method for PMT afterpulse rates in the SUBMET experiment that achieves approximately 20% precision, thereby enhancing the reliability of background predictions for the search of millicharged particles.
Using a dataset of 428 fb collected by the Belle II experiment, researchers measured the time- and phase-space-integrated asymmetry in decays to be , which represents the most precise result to date and is consistent with conservation.
This paper presents next-to-next-to-leading order (NNLO) QCD evaluations of proton and pion mass decompositions using gravitational form factors, comparing standard quark/gluon and trace-anomaly breakdowns with a novel twist-two/twist-four separation to demonstrate its advantages and reveal distinct parton-correlation behaviors between the two hadrons.
