论文摘要

对主要软可观察物的最新结果,包括强子和光子的产量和颗粒数比,$ p_t $ spectra,流量谐波以及在集成的水文模型(IHKM)内获得的高能重型离子碰撞次数在集成的水力学模型(IHKM)内获得的结果。考虑了不同能量碰撞的不同核的病例:au+au碰撞在最高的rhic能量$ \ sqrt {s_ {nn}} = 200 $ gev,pb+pb collisision lhc energies $ \ sqrt {sqrt {s_ {s_ {nn}} = 2.76 $ TEV和TEV和TEV和TEV和TEV和TEV和$ \ sqrt {s_ {nn}} = 5.02 $ tev和lhc Xe+Xe collisions $ \ sqrt {s_ {nn}} = 5.44 $ tev。讨论了初始条件和模型参数的影响,包括夸克 - 格鲁恩相的状态方程(EOS)对仿真结果的影响以及物质演化的最终燃烧阶段的作用。考虑了所谓的``光子拼图''的可能解决方案。还要注意干涉量体积的依赖性和单个干涉测定法对碰撞中形成的系统的初始横向几何大小的依赖性。

The recent results on the main soft observables, including hadron and photon yields and particle number ratios, $p_T$ spectra, flow harmonics, as well as the femtoscopy radii, obtained within the integrated hydrokinetic model (iHKM) for high-energy heavy-ion collisions are reviewed and re-examined. The cases of different nuclei colliding at different energies are considered: Au+Au collisions at the top RHIC energy $\sqrt{s_{NN}}=200$ GeV, Pb+Pb collisions at the LHC energies $\sqrt{s_{NN}}=2.76$ TeV and $\sqrt{s_{NN}}=5.02$ TeV, and the LHC Xe+Xe collisions at $\sqrt{s_{NN}}=5.44$ TeV. The effect of the initial conditions and the model parameters, including the utilized equation of state (EoS) for quark-gluon phase, on the simulation results, as well as the role of the final afterburner stage of the matter evolution are discussed. The possible solution of the so-called ``photon puzzle'' is considered. The attention is also paid to the dependency of the interferometry volume and individual interferometry radii on the initial transverse geometrical size of the system formed in the collision.
