In the hydrodynamic model description of heavy-ion collisions, elliptic flow v_{2} and triangular v_{3} are sensitive to quadrupole deformation β_{2} octupole β_{3} colliding nuclei. The relations between v_{n} β_{n} have recently been clarified were found follow a simple parametric form. STAR Collaboration has just published precision data from isobaric ^{96}Ru+^{96}Ru ^{96}Zr+^{96}Zr where they observe large differences in central collisions v_{2,Ru}>v_{2,Zr} v_{3,Ru}<v_{3,Zr}. Using...
Multi-particle azimuthal cumulants, often used to study collective flow in high-energy heavy-ion collisions, have recently been applied small collision systems such as $pp$ and $p$+A extract the second-order harmonic $v_2$. Recent observation of four-, six- eight-particle cumulants with "correct sign" $c_2\{4\}<0, c_2\{6\}>0, c_2\{8\}<0$ approximate equality inferred single-particle flow, $v_2\{4\}\approx v_2\{6\}\approx v_2\{8\}$, strong evidence for a emission all soft particles produced...
In the hydrodynamic framework of heavy-ion collisions, elliptic flow v_{2} is sensitive to quadrupole deformation β colliding ions. This enables one test whether established knowledge on low-energy structure nuclei consistent with collider data from high-energy experiments. We derive a formula based generic scaling laws hydrodynamics relate difference in measured between collision systems that are close size value respective species. validate our simulations ^{238}U+^{238}U and...
The author presents compelling arguments that measurements of collective flow in high-energy nuclear collisions can provide information on the shape atomic nuclei time scales several orders magnitude shorter than are probed low-energy experiments.
The structure of atomic nuclei is shown to influence a collection observables measured in relativistic heavy-ion collisions. Details the nuclear shape---here its triaxial nature---and fluctuations are reflected angular correlations between detected particles, establishing connection high-energy collisions and low-energy structure.
Bulk nuclear structure properties, such as radii and deformations, leave distinct signatures in the final state of relativistic heavy-ion collisions. Isobaric collisions offer an easy route to establish explicit connections between colliding nuclei's observable outcomes. Here, we investigate effects skin thickness deformations on elliptic flow ($v_2$) its fluctuations high-energy $^{96}$Ru+$^{96}$Ru $^{96}$Zr+$^{96}$Zr Our findings reveal that difference these isobars only influences...
In high-energy heavy-ion collisions, the initial condition of produced quark-gluon plasma (QGP) and its evolution are sensitive to collective nuclear structure parameters describing shape radial profiles nuclei. We find a general scaling relation between these many experimental observables such as elliptic flow, triangular particle multiplicity distribution. particular, ratios two isobar systems depend only on differences parameters, but not details final state interactions, hence offering...
The past decade has seen huge advances in experimental measurements made heavy ion collisions at the Relativistic Heavy Ion Collider (RHIC) and more recently Large Hadron (LHC). These new data, combination with theoretical from calculations a variety of frameworks, have led to broad deep knowledge properties thermal QCD matter. Increasingly quantitative descriptions quark-gluon plasma (QGP) created these established that QGP is strongly coupled liquid lowest value specific viscosity ever...
We argue that the transverse shape of fireball created in heavy-ion collision could be strongly influenced by event-by-event fluctuations eccentricity vectors for forward-going and backward-going wounded nucleons: ${\stackrel{P\vec}{\ensuremath{\epsilon}}}_{n}^{\mathrm{F}}\ensuremath{\equiv}{\ensuremath{\epsilon}}_{n}^{\mathrm{F}}{e}^{in{\ensuremath{\Phi}}_{n}^{*\mathrm{F}}}$...
In heavy ion collisions, elliptic flow $v_2$ and radial flow, characterized by event-wise average transverse momentum $[p_{\mathrm{T}}]$, are related to the shape size of overlap region, which sensitive colliding atomic nuclei. The Pearson correlation coefficient between $\rho_2$, was found be particularly quadrupole deformation parameter $\beta$ that is traditionally measured in low energy experiments. Built on earlier insight prolate $\beta>0$ reduces $\rho_2$ ultra-central collisions...
A collision between two atomic nuclei accelerated at a speed close to that of light creates dense system quarks and gluons. Interactions among them are so strong they behave collectively like droplet fluid ten-femtometer size, which expands into the vacuum eventually fragments thousands particles. We report new manifestation thermalization in recent data from Large Hadron Collider. Our analysis is based on results ATLAS Collaboration, has measured variance momentum per particle across...
Abstract High-energy nuclear collisions encompass three key stages: the structure of colliding nuclei, informed by low-energy physics, initial condition , leading to formation quark–gluon plasma (QGP), and hydrodynamic expansion hadronization QGP, final-state hadron distributions that are observed experimentally. Recent advances in both experimental theoretical methods have ushered a precision era heavy-ion collisions, enabling an increasingly accurate understanding these stages. However,...

In modern industrial production, enterprises face the dual challenge of ensuring supply chain quality reliability while controlling costs. Traditional single-link detection methods are inadequate for multi-link collaborative decision-making in chains. This study proposes a inspection method combining binomial distribution and Monte Carlo simulation enterprise production processes. Integrating hypothesis testing based on normal determines whether spare part defective rates exceed...
I review recent measurements of a large set flow observables associated with event-shape fluctuations and collective expansion in heavy ion collisions. First, these are classified experiment methods introduced. The experimental results for each type then presented compared to theoretical calculations. A coherent picture initial condition based on linear non-linear hydrodynamic responses is derived, which qualitatively describe most results. discuss new types fluctuation that can further our...
Nuclides sharing the same mass number (isobars) are observed ubiquitously along stability line. While having nearly identical radii, stable isobars can differ in shape, and present particular different quadrupole deformations. We show that even small differences these deformations be probed by relativistic nuclear collisions experiments, where they manifest as deviations from unity ratios of elliptic flow coefficients taken between isobaric systems. Collider experiments with represent, thus,...
The ratios of bulk observables, such as harmonic flow ${v}_{2}$ and ${v}_{3}$, between high-energy $^{96}\mathrm{Ru}+^{96}\mathrm{Ru}$ $^{96}\mathrm{Zr}+^{96}\mathrm{Zr}$ collisions were recently argued to be a clean probe the nuclear structure differences $^{96}\mathrm{Ru}$ $^{96}\mathrm{Zr}$. Using transport model simulation isobar collisions, we quantify this claim from dependence ${v}_{2,\mathrm{Ru}}/{v}_{2,\mathrm{Zr}}$ ${v}_{3,\mathrm{Ru}}/{v}_{3,\mathrm{Zr}}$ on various final-state...

Machine learning offers a powerful framework for validating and predicting atomic mass. We compare three improved neural network methods representation extrapolation mass prediction. The method, adopting macroscopic-microscopic approach treating complex nuclear effects as output labels, achieves superior accuracy in AME2020, yielding much lower root-mean-square deviation of 0.122 MeV the test set, significantly than alternative methods. It also exhibits better performance when AME2020 from...
Currently, the utilization of semi-overlap functions has become increasingly widespread in constructing fuzzy rough sets. However, intuitionistic set models, grounded functions, and their applications have not been studied. Therefore, this paper introduces a novel β⋆-covering model that builds upon applies it to address multi-criteria decision-making challenges. Initially, we present concepts (semi-grouping) subsequently develop four β⋆-neighborhood operators. Next, propose some new models...
