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.
The STAR experiment at RHIC presents high-statistics femtoscopy results from Isobar and Au+Au collisions, revealing an attractive interaction in - pairs and a bound state in - pairs through the analysis of final-state correlations.
This paper presents the first systematic investigation of heavy-flavor fragmentation into fully charmed or bottomed tetraquarks across scalar, axial vector, and tensor configurations using a nonrelativistic QCD framework, while propagating uncertainties from long-distance matrix elements to advance the understanding of exotic matter formation.
This review extends the study of inclusive vector quarkonium production at the LHC using the JETHAD method and a hybrid NLL/NLO factorization approach, demonstrating enhanced stability in forward rapidity regions and offering a unique opportunity for precision high-energy QCD studies and resolving the quarkonium production puzzle.
This paper reviews the semi-inclusive hadroproduction of neutral hidden-flavor tetraquarks at the HL-LHC using the JETHAD framework and novel TQHL1.0 fragmentation functions, demonstrating that high-energy observables for these exotic states remain stable under radiative corrections and providing a crucial link between QCD resummation techniques and exotic matter research.
This paper reviews and extends the application of the JETHAD method to analyze the NLL/NLO+ behavior of light and heavy hadron production in forward and far-forward rapidity ranges, demonstrating the stabilization of semi-inclusive heavy hadron detections against higher-order corrections and exploring kinematic regions accessible at current LHC experiments and future Forward Physics Facilities.
This paper extends active learning emulators with error estimation to coupled-channel nuclear two-body scattering in momentum space by employing Lippmann-Schwinger-based reduced-order models trained via greedy algorithms, demonstrating high accuracy and computational speedup for phase shifts and cross sections to facilitate future Bayesian calibrations of nuclear interactions.
This paper proposes a novel pathway to nuclear fusion breakeven using electron-free targets in beam-target interactions, which drastically reduce stopping power to allow fusion energy output to exceed beam energy deposition without requiring extreme plasma confinement.
This study presents the first experimental measurements of the Au(,pn)Pt photonuclear cross section near its threshold using the HIS facility, revealing that the reaction becomes measurable only around 30 MeV and requires significantly higher energies for practical production of therapeutic platinum isotopes.
This paper refines theoretical predictions for light-by-light scattering by improving two-loop helicity amplitudes with asymptotic expansions and Coulomb resummation, providing state-of-the-art Standard Model cross-section calculations and a new Monte Carlo event generator named LbLatNLO.
This paper presents continuum-estimated (2+1)-flavor lattice QCD results demonstrating that the baryon-electric charge correlation serves as a sensitive magnetometer for strong magnetic fields, while also mapping the equation of state up to and constructing detector-compatible observables to bridge theoretical predictions with experimental heavy-ion collision data.
