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 ψ(2S)ψ(2S) production at midrapidity in pp collisions at s=13\sqrt{s} = 13 TeV

This paper presents the first measurement of inclusive ψ(2S)\psi(2S) production at midrapidity in pp collisions at s=13\sqrt{s} = 13 TeV using the ALICE detector, reporting the transverse-momentum differential cross section and its ratio to J/ψ\psi production, which reveals a mild rise in the ratio with increasing pTp_{\rm T} and is compared with NRQCD and ICEM theoretical models.

Measurement of π0π^0-hadron correlations relative to the event plane in semicentral Pb-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV

In semicentral Pb-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV, ALICE measurements of π0\pi^0-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.

Measurement of the charged-particle-jet transverse-momentum fraction carried by prompt and non-prompt J/ψψ mesons in pp collisions at s=13\sqrt{s}=13 TeV

The ALICE Collaboration reports the first measurement of the charged-particle jet transverse-momentum fraction (zchz^{\rm ch}) carried by prompt and non-prompt J/ψ\psi mesons in 13 TeV proton-proton collisions, revealing that while PYTHIA 8 simulations qualitatively reproduce the data for zch<0.9z^{\rm ch} < 0.9, they significantly overestimate the fraction of isolated J/ψ\psi mesons at high zchz^{\rm ch} values, highlighting challenges in modeling the hadronization of low-momentum jets.

Measurements of the production of W±^{\pm} and Z0^0 bosons in pp collisions at s=13\sqrt{s} = 13 TeV

This paper presents ALICE measurements of W±^{\pm} and Z0^0 boson production cross sections in pp collisions at s=13\sqrt{s} = 13 TeV via their electronic decay channels, comparing the results with perturbative QCD calculations and reporting the first LHC observation of W±^{\pm} production and associated hadrons as a function of charged-particle multiplicity.

Limits on the chiral magnetic effect from the event shape engineering and participant-spectator correlation techniques in Pb-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV

This paper presents the latest ALICE results from Pb-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV, utilizing event shape engineering and participant-spectator correlation techniques to measure charge-dependent correlations and establish upper limits consistent with the absence of a Chiral Magnetic Effect signal.

Understanding the impact of nuclear effects on proton decay searches with the GiBUU model

This study utilizes the GiBUU framework to demonstrate that while pion final-state interactions have a moderate impact on proton decay search sensitivity in water Cherenkov detectors, the choice of Fermi momentum distribution constitutes the dominant systematic uncertainty affecting atmospheric neutrino background estimates.

Universal and non-universal finite-volume effects in the vicinity of chiral phase transition in (2+1)-flavor QCD

This paper presents a finite-size scaling analysis of the chiral order parameter in (2+1)-flavor QCD using HISQ lattice data, demonstrating that infinite-volume extrapolated results align with expected O(2)O(2) scaling behavior while quantifying finite-size deviations to improve the precision of chiral phase transition temperature determinations.
