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 proposes a scaling approach using triangular flow fluctuations in relativistic U+U collisions to extract the mean and variance of octupole deformation, thereby distinguishing between static and vibrational nuclear deformation origins and refining quark-gluon plasma initial conditions.
This paper introduces a stochastic Similarity Renormalization Group framework (SRGQMC) that integrates quantum Monte Carlo techniques to overcome the computational limitations of deterministic many-body flow equations, enabling the first successful IMSRG(4) calculations and providing a practical pathway toward higher-order many-body nuclear structure computations.
This study quantifies how uncertainties in nuclear level densities and photon strength functions, particularly those arising from local parameter variations in photoneutron emission rates, propagate to limit the precision of p-process nucleosynthesis predictions in Type-Ia and Type-II supernovae, identifying specific reactions involving stable or near-stable nuclei as primary targets for future experimental constraints.
This paper calculates tensor-polarized parton distribution functions for the deuteron using a convolution model, revealing significant discrepancies with existing HERMES data that suggest the need for new theoretical mechanisms beyond a simple proton-neutron bound system, while providing predictions for upcoming experimental tests at Jefferson Lab and Fermilab.
This paper investigates how the running of the QCD coupling affects anti-collinear resummation in JIMWLK evolution, deriving a resummed BFKL kernel that reveals a significant reduction in the Pomeron intercept due to combined resummation and coupling effects, despite a surprising cancellation that leaves the characteristic function at unchanged.
This paper theoretically demonstrates that Maris polarization, an effective polarization arising from nuclear absorption and spin-orbit coupling, can be observed in the proton-induced deuteron knockout (p,pd) reaction at 250 MeV through the vector analyzing power , thereby offering a method to determine the total angular momentum of deuteron-cluster orbits.
This paper investigates how collision-induced QED radiation affects Standard Model Effective Field Theory (SMEFT) constraints in deep-inelastic scattering, revealing that while cross sections undergo significant order-one corrections, longitudinal electron spin asymmetries remain robust at the few-percent level, thereby offering a more reliable observable for future precision studies at facilities like SoLID and the Electron-Ion Collider.
This paper proposes that the annual modulation observed in the DAMA/LIBRA experiment could be explained not by dark matter, but by a gravitational chiral anomaly in the Sun's Kerr field that produces a strictly node-locked phase (June 7–8) with no astrophysical freedom, offering a testable alternative hypothesis distinguishable from the standard halo model through high-precision phase metrology and energy independence checks.
The AMoRE-I experiment analyzed 7.32 kgyr of exposure from thirteen CaMoO crystals to search for neutrinoless double electron capture in Ca, finding no significant signal and setting a lower half-life limit of years at 90% confidence level.
The authors develop a microscopic reaction model combining discrete basis and shell model approaches to simultaneously describe the contrasting fusion cross-section behaviors of the C+C and C+C systems at astrophysical energies by explicitly treating entrance channel and compound nucleus states.
