论文摘要
在LHC能量的HADRONIC碰撞中，可以通过低阶项表达如何在独立的局部过程中产生粒子 - 抗粒子对，可以通过低阶项来表达在LHC能量下的HADRONIC碰撞中的净荷兰分布的高阶累积分布。通过HIJING模型进行了争论和测试，即在系统中不存在关键行为的情况下，此假设通常对于净质子波动有效。以这种方式估计的值可以被视为实际数据中高阶净电荷波动直接测量的基准。
It is shown how high-order cumulants of net-charge distribution in hadronic collisions at LHC energies can be expressed via lower-order terms under the assumption that particle-antiparticle pairs are produced in independent local processes. It is argued and tested with HIJING model that this assumption is typically valid for net-proton fluctuations in the case when no critical behaviour is present in the system. Values estimated in such a way can be considered as baselines for direct measurements of high-order net-charge fluctuations in real data.
