Nucl-Ex represents the dynamic frontier where scientists probe the fundamental building blocks of matter through high-energy experiments. By smashing particles together at incredible speeds or observing rare cosmic events, researchers uncover the forces that govern our universe and test the limits of our current understanding of physics.
At Gist.Science, we ensure these breakthroughs reach a broader audience by processing every new preprint in this field directly from arXiv. For each study, we provide both a clear, plain-language explanation of the core discoveries and a detailed technical summary for those seeking deeper insights. Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.
This paper presents a comparative simulation study using Geant4 and FLUKA to benchmark and optimize a 30 MeV proton-induced beryllium neutron source, evaluating neutron fluence, gamma dose, and moderation effects to guide the design of a modular irradiation station for thermal neutron fields.
This review examines a decade of theoretical and experimental advancements in muon physics, highlighting global efforts to enhance sensitivity in studying muon decays, magnetic and electric dipole moments, and charged lepton flavor violation to probe New Physics scenarios and guide future facility proposals.
This paper establishes a new benchmark for heavy-quark TMD resummation at the LHC by developing a framework that combines SCET and HQET to achieve NNLL' accuracy for the azimuthal decorrelation of boosted top quark pairs, a feat made possible by the first extraction of the two-loop ultra-collinear function.
This paper proposes that ultra-peripheral ion collisions generate entangled multi-particle states through shared photon polarization, leading to distinct azimuthal angular correlations that differ significantly between classical and quantum predictions and offer new avenues for testing multi-particle entanglement.
This study presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using boosted correlators in the Coulomb gauge, demonstrating that the method yields results compatible with global analyses for valence-quark distributions while highlighting the need to address excited-state contamination in full-quark-channel extractions.
This paper presents a detailed description of the NEXT-100 detector's design, assembly, and radiopurity budget, alongside results from its commissioning run at the Laboratorio Subterráneo de Canfranc, which demonstrated stable operation and effective monitoring using alpha decays.
This study utilizes the Jet AA Microscopic Transport Model to demonstrate that -clustering in nuclei enhances geometric compactness and radial observables like proton mean transverse momentum, as well as flow magnitudes at high participant numbers, thereby offering complementary probes for investigating nuclear structure in low-energy collisions at CSR and HIAF energies.
This paper presents the first observation of significant transverse momentum and pseudorapidity dependent flow vector fluctuations in p$-$Pb collisions at TeV, confirming collective flow in small collision systems and providing critical constraints for theoretical models of initial geometry.
This paper presents the first measurements of inclusive and multiplicity-dependent pseudorapidity densities of charged particles in proton-proton collisions at the record center-of-mass energy of TeV, revealing that particle production in high-multiplicity events follows a power-law scaling with energy and establishing a new reference for LHC physics.
This paper demonstrates that a high-precision, distributed source can be used to accurately verify the effective mass and volume of an HPGe detector by comparing experimental gamma-ray spectra with Geant4 Monte Carlo simulations.
