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.

Inclusive charm and bottom quark pair production cross sections at hadron colliders at next-to-next-to-leading-order accuracy

This paper presents a comprehensive study of inclusive charm and bottom quark pair production cross sections across a wide range of collision energies using next-to-next-to-leading-order (NNLO) calculations with the new MaunaKea code, demonstrating that these advanced predictions significantly enhance accuracy and reduce theoretical uncertainties compared to previous NLO results, thereby achieving agreement with experimental data and offering valuable constraints on gluon density and the bottom-quark mass.

Characterization of nuclear breakup as a function of hard-scattering kinematics using dijets measured by ATLAS in pp+Pb collisions

Using 8.16 TeV pp+Pb collision data from the ATLAS detector, this study demonstrates that event geometry estimators based on forward energy deposition are sensitive to the initial-state hard-scattering kinematics, specifically showing a strong dependence on the proton-side parton's Bjorken-xx that is significantly more pronounced in the Forward Calorimeter than in the Zero-Degree Calorimeter.

Collective effects in O-O and Ne-Ne collisions at sNN\sqrt{s_{\mathrm{NN}}}=5.36 TeV from a hybrid approach

This study employs a hybrid approach alongside pure hadronic and string models to predict collective effects in upcoming O-O and Ne-Ne collisions at the LHC, aiming to determine the onset of quark-gluon plasma formation in small collision systems by comparing hydrodynamic and non-hydrodynamic evolutions.

First investigation of 96^{96}Zr samples enriched by the gas-centrifuge method for the use in rare-decay studies

This paper reports the first production of gas-centrifuge-enriched 96^{96}Zr samples and their subsequent low-background investigation, which established a new, stringent half-life limit of T1/2>3.9×1019T_{1/2} > 3.9 \times 10^{19} years for the double beta decay of 96^{96}Zr to the 01+0^+_1 excited state of 96^{96}Mo.

Exclusive dimuon production and coherent charmonium photoproduction at forward rapidity in ultra-peripheral Pb$-$Pb collisions at sNN=5.36\mathbf{\sqrt{s_{\rm NN}}=5.36} TeV

Using 2023 ALICE data from ultra-peripheral Pb–Pb collisions at sNN=5.36\sqrt{s_{\rm NN}}=5.36 TeV, this paper presents forward rapidity measurements of coherent J/ψ\psi and ψ\psi(2S) photoproduction and exclusive dimuon production, revealing significant nuclear shadowing effects in quarkonium production and highlighting the sensitivity of dimuon measurements to photon flux modeling near the nuclear radius.

Glauber quark and gluon contributions to quark energy loss at next-to-leading order and next-to-leading twist

This paper computes all possible medium-induced single-scattering emission kernels for an energetic virtual quark traversing a nuclear environment at next-to-leading order and next-to-leading twist, incorporating heavy-quark mass effects, Glauber quark and gluon interactions, and coherence effects to derive four distinct collisional scattering kernels with full phase factors and gradient expansions.

Neutron star crust and outer core equation of state from chiral effective field theory with quantified uncertainties

This paper employs a Bayesian framework with a two-dimensional Gaussian process to quantify chiral effective field theory uncertainties in the equation of state for asymmetric nuclear matter up to twice saturation density, thereby constructing consistent models for the inner crust and outer core of neutron stars.

The ICESPICE demonstrator for particle/γ\gamma-e−e^{-} coincidence experiments at Florida State University

The ICESPICE demonstrator, a modular mini-orange spectrometer developed at Florida State University, successfully enables particle/gamma-electron coincidence measurements for low-energy nuclear structure studies, as validated by commissioning tests and its first in-beam application with the Super-Enge Split-Pole Spectrograph.
