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 general methods for extracting transverse single-spin asymmetries using both binned and unbinned maximum likelihood approaches, specifically designed to address experimental challenges such as time-varying polarization, unequal spin-state luminosities, and the need for background subtraction and kinematic unfolding.
This report synthesizes the outcomes of the 2025 EIC-France Workshop, outlining theoretical advancements and strategic priorities for the French hadron-physics community, with a specific focus on immediate opportunities in inclusive diffraction and quarkonium production alongside longer-term goals in pion structure and exclusive three-body final states.
This study presents the first measurement of charged-particle nuclear modification factors in neon-neon collisions and systematically compares them with oxygen-oxygen, xenon-xenon, and lead-lead data to demonstrate that charged-particle suppression scales with nuclear size and is well-described by energy loss models rather than initial-state nuclear effects.
This study demonstrates that correcting for "geometric inflation" artifacts in initial-state modeling of relativistic heavy-ion collisions significantly alters the sensitivity of final-state observables to nucleon size, thereby preventing biases in the extraction of nucleon structure and quark-gluon plasma properties.
This paper presents a fully microscopic multichannel Resonating Group Method description of the 12C+12C fusion reaction at stellar energies, which successfully reproduces experimental scattering data, reveals the mixed nature of 24Mg resonances, predicts fusion hindrance at low energies, and lays the groundwork for reliable theoretical extrapolations to deep stellar burning temperatures.
This paper presents the first measurement of inclusive production at midrapidity in pp collisions at TeV using the ALICE detector, reporting the transverse-momentum differential cross section and its ratio to J/ production, which reveals a mild rise in the ratio with increasing and is compared with NRQCD and ICEM theoretical models.
In semicentral Pb-Pb collisions at TeV, ALICE measurements of -hadron correlations relative to the event plane show no significant dependence, a result that aligns with JEWEL model predictions but suggests the potential existence of energy-loss mechanisms beyond simple path-length dependence.
This paper presents the first measurement of deuteron coalescence parameters in p-Pb collisions at 5.02 TeV, revealing a significant enhancement of the coalescence parameter within jets compared to the underlying event, a finding that exceeds similar observations in pp collisions and is qualitatively reproduced by PYTHIA 8.314 simulations.
The ALICE Collaboration reports the first measurement of the charged-particle jet transverse-momentum fraction () carried by prompt and non-prompt J/ mesons in 13 TeV proton-proton collisions, revealing that while PYTHIA 8 simulations qualitatively reproduce the data for , they significantly overestimate the fraction of isolated J/ mesons at high values, highlighting challenges in modeling the hadronization of low-momentum jets.
This paper presents ALICE measurements of W and Z boson production cross sections in pp collisions at TeV via their electronic decay channels, comparing the results with perturbative QCD calculations and reporting the first LHC observation of W production and associated hadrons as a function of charged-particle multiplicity.
