Abstract

Experimental data on transverse momentum spectra of charged hadrons, strange particles, top quark and jets produced in \(p + p\) and \(\bar {p} + p\) collisions obtained at RHIC, Tevatron, and LHC are analyzed in the framework of \(z\)-scaling approach. The concept of the \(z\)-scaling based on fundamental principles of self-similarity, locality, and fractality of hadron interactions is verified over a wide range of collision energy and transverse momentum for different particle species. General properties of the data \(z\)-presentation are reviewed. A microscopic scenario of constituent interactions developed within the \(z\)-scaling scheme is used to study the dependence of momentum fractions and recoil mass on the collision energy, transverse momentum and mass of produced inclusive particle, and to estimate the constituent energy loss. Results of analysis in the framework of \(z\)-scaling of the negative particle spectra in \({\text{Au}} + {\text{Au}}\) collisions obtained by the STAR Collaboration in the first phase of the Beam Energy Scan program at RHIC are presented. New indication on self-similarity of fractal structure of nuclei and fragmentation processes is found.

在RHIC,Tevatron和LHC的p + p,$$ \ bar {p} + p $$和Au + Au碰撞中z缩放的验证

摘要

分析了在RHIC,Tevatron和LHC碰撞中获得的\(p + p \)\(\ bar {p} + p \)碰撞中产生的带电强子,奇异粒子,顶夸克和射流的横向动量谱的实验数据。\(z \)-缩放方法的框架。基于自相似性,局部性和强子相互作用的分形性的基本原理的\(z \)缩放的概念在不同的粒子种类的大范围碰撞能量和横向动量上得到了验证。回顾了数据\(z \)-表示的一般属性。在\(z \)内形成的成分相互作用的微观场景比例缩放法用于研究动量分数和反冲质量对碰撞能量,横向动量和产生的包容颗粒质量的依赖性,并估计组成能量的损失。在()的第一阶段由STAR Collaboration获得的\({\ text {Au}} + {\ text {Au}} \)碰撞中负粒子光谱的\(z \)缩放尺度下的分析结果。介绍了RHIC的束能量扫描程序。发现了核分形结构的自相似性和断裂过程的新迹象。
