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 establishes a new universal relation linking the electric dipole polarizability of finite nuclei to the compactness of neutron stars, enabling the use of nuclear experimental data to constrain the neutron star radius and the slope of the symmetry energy in an equation-of-state independent manner.
This study demonstrates that the structural and electrical resilience of graphene-based materials under 60 MeV 35Cl ion irradiation depends critically on their initial order, with highly oriented pyrolytic graphite (HOPG) suffering progressive degradation while multilayer reduced graphene oxide (ML-rGO) exhibits potential for radiation-induced structural reorganization and enhanced ordering.
This paper reviews the physical mechanisms and bottlenecks of muon-catalyzed fusion, proposes a synergistic four-step scheme to overcome alpha-sticking and achieve energy gain, and outlines a conceptual fusion-fission hybrid reactor design for breeding plutonium.
This study demonstrates that the directed flow () of charm quarks in asymmetric Cu+Au collisions is significantly enhanced compared to light hadrons and serves as a sensitive probe for both the initial spatial distribution of heavy quarks and temperature-dependent medium transport coefficients.
This paper presents complete isotopic fission yield distributions of Pu measured as a function of excitation energy (8.2–11.9 MeV), revealing that increasing excitation energy dampens shell effects in the symmetry valley and reduces neutron content specifically in heavy fragments while leaving light fragments unaffected.
This LHCb study of meson production in NeNe and OO collisions at 5.36 TeV reveals a transverse momentum-dependent variation inconsistent with nuclear structure modifications alone, providing evidence for the onset of quark-gluon plasma formation in light-ion collisions.
This paper proposes a novel method to detect light-quark Yukawa couplings to the Higgs boson by measuring unique azimuthal modulations in fragmentation products, termed Yukawa Fragmentation Asymmetries, which offer improved sensitivity and theoretical control compared to existing techniques.
The RadioAxion experiment, conducted underground at the Gran Sasso Laboratory using a NaI detector to monitor the 59.5 keV gamma line of Am alpha decay, reports no evidence of periodic modulations indicative of axion dark matter and consequently establishes new constraints on the axion decay constant for masses between and eV.
This paper demonstrates that the CITIUS high-speed X-ray detector, originally developed for synchrotron radiation, effectively images heavy charged particles and neutrons with significantly improved spatial resolution by leveraging its gain-selecting architecture and long carrier drift distance to manage charge diffusion.
Through the first observation of a weak -delayed transition using high-quality beams at FRIB, researchers determined that the Al ground state has spin and parity, which prevents proton halo formation due to a dominant -wave centrifugal barrier despite its low proton separation energy.
