摘要
相对论重离子碰撞的扩散模型相对论重离子碰撞是研究量子多体系统部分接近统计平衡的多功能工具。在编号为 2300307 的文章中，约翰内斯-霍尔克（Johannes Hölck）和格奥尔格-沃尔斯钦（Georg Wolschin）明确而严格地推导出了随机福克-普朗克方程（the stochastic Fokker-Planck equation for the momentum distribution function of produced charged hadrons in longitudinal and transverse rapidities），从而为相对论扩散模型奠定了坚实的统计基础。该模型用于分析大型强子对撞机 LHC 所达到的能量下的 Pb-Pb 对撞。详细比较了 ATLAS 和 ALICE 协作在横向动量和假振幅空间的数据。
Diffusion Model for Relativistic Heavy-Ion Collisions
Relativistic heavy-ion collisions are a versatile tool to study the partial approach of a quantum many-body system towards statistical equilibrium. In article number 2300307, Johannes Hölck and Georg Wolschin present an explicit and rigorous derivation of the stochastic Fokker–Planck equation for the momentum distribution function of produced charged hadrons in longitudinal and transverse rapidities, thus placing the relativistic diffusion model on a firm statistical foundation. The model is used to analyse Pb–Pb collisions at energies reached at the Large Hadron Collider LHC. Detailed comparisons with data from the ATLAS and ALICE collaborations in transverse-momentum and pseudorapidity space are given.
期刊介绍：
Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
