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 the first measurements of dielectron production in proton-proton and proton-lead collisions at = 5.02 TeV using the ALICE detector, determining charm and beauty cross sections in pp collisions and finding that the pPb results are consistent with expectations without nuclear matter effects while providing the first direct comparison of these systems via the nuclear modification factor .
By modeling resonance decay effects on pion and kaon-proton correlations in 13 TeV pp collisions, this study demonstrates that a universal, collectively scaling primordial emission source exists for all hadron species in small collision systems at the LHC.
The ALICE Collaboration measured the inclusive production cross section of isolated prompt photons in pp and p-Pb collisions at various LHC energies, observing a low-transverse-momentum suppression in p-Pb collisions consistent with nuclear shadowing effects predicted by perturbative QCD.
The ALICE collaboration at the LHC has provided model-independent evidence that approximately 90% of deuterons and antideuterons in high-energy proton-proton collisions are formed via nuclear reactions following the decay of short-lived resonances, thereby resolving a key gap in understanding light (anti)nuclei production in ultra-relativistic environments.
Using LHCb data from Pb and Pb collisions at TeV, this study measures the to production ratio as a function of multiplicity, revealing a multiplicity-dependent suppression for prompt charmonia in the Pb-going direction that suggests the presence of additional mechanisms, potentially related to quark-gluon plasma formation, beyond standard comover effects.
The ALICE experiment measured the transverse momentum spectra and integrated yields of anti- hyperons in pp and p-Pb collisions at TeV using a novel antineutron reconstruction method, finding that while multiparton-interaction models best describe the high- spectra, all tested models reproduce the total yields and nuclear modification factors within uncertainties.
This paper reports on the multiplicity dependence of f(980) production in pp collisions at TeV using the ALICE detector, finding that yield ratios decrease with increasing multiplicity and that thermal model comparisons suggest the f(980) does not contain significant hidden strangeness.
This paper presents the first measurement of production in minimum-bias and high-multiplicity pp collisions at TeV using a novel reconstruction method that combines converted and calorimeter photons, providing transverse-momentum spectra and ratios that agree with theoretical models and enabling future femtoscopic studies relevant to neutron star physics.
This paper introduces SVAROG, a compact neutron supermirror transmission multichannel polarizer with an electromagnetic system, detailing its fundamental properties, potential applications at the PIK research reactor, and a comparative analysis with existing neutron transmission polarizers.
This study investigates the temperature dependence of electron-drift anisotropy in n-type germanium detectors, revealing that standard drift models yield unphysical predictions and proposing a modified model that better aligns with experimental data obtained from surface scans at varying temperatures.
