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 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 reports a high-precision measurement of the D(, )p photodisintegration reaction at SLEGS, which, when combined with theoretical analysis, significantly reduces uncertainties in the Big-Bang Nucleosynthesis baryon density parameter while revealing a persistent tension between primordial deuterium observations and Cosmic Microwave Background measurements.
This paper reports the successful commissioning of the Resonance Ionization Spectroscopy Experiment (RISE) at FRIB's BECOLA facility, which integrates new beamline components and laser systems to enable sensitive measurements of isotope shifts and hyperfine structure in short-lived isotopes, as demonstrated by initial tests on stable Al.
This paper reviews the current status of the muon anomalous magnetic moment as a probe for physics beyond the Standard Model following the final FNAL results and the second Theory Initiative White Paper, while discussing experimental achievements, ongoing efforts to improve theoretical predictions, and future prospects for surpassing current precision limits.
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 demonstrates that event-by-event fluctuations and rapidity decorrelation of mean transverse momentum in baryon-dense media are driven by energy and net-baryon density fluctuations rather than baryon diffusion, establishing the observable as a robust probe of the equation of state while revealing distinct flow dynamics between protons and antiprotons.
This paper proposes a method to locate the QCD critical point by analyzing contours of constant entropy density extrapolated from zero net-baryon density, yielding a predicted critical point at MeV and MeV based on Wuppertal–Budapest lattice QCD data.
This paper demonstrates that proton-proton scattering at specific kinematic conditions (151 MeV, 90°) naturally generates a high-fidelity Bell-triplet entangled state, enabling a proposed quantum teleportation protocol that utilizes the strong interaction's intrinsic Hamiltonian to perform Bell measurements.
This paper reveals that higher-order cumulants mixing elliptic and triangular flow in Pb+Pb collisions exhibit a surprising simplicity at fixed impact parameter, where their variations are solely determined by the mean elliptic flow from the collision geometry, leading to analytic relations that agree well with CMS data and enable predictions for higher-order cumulants.
