论文摘要
测量了质量 - 质量不弹性散射的带电粒子多重性分布，在质量中心$ \ sqrt {s} = 319 $ gev处被测量。数据与H1检测器在HERA收集，对应于$ 136 $ PB $ {}^{ - 1} $的集成光度。带电的粒子多重性是根据光子虚拟性$ q^2 $，非弹性$ y $和伪质$η$的函数测量的。将来自不同蒙特卡洛模型的预测与数据进行了比较。确定了多样性分布的第一和第二矩，并研究了KNO缩放行为。多重分布作为$ q^2 $的函数和Bjorken变量$ x _ {\ rm bj} $转换为强子熵$ s _ {\ rm HADRON} $，并测试了量子纠缠模型的预测。
Charged particle multiplicity distributions in positron-proton deep inelastic scattering at a centre-of-mass energy $\sqrt{s}=319$ GeV are measured. The data are collected with the H1 detector at HERA corresponding to an integrated luminosity of $136$ pb${}^{-1}$. Charged particle multiplicities are measured as a function of photon virtuality $Q^2$, inelasticity $y$ and pseudorapidity $η$ in the laboratory and the hadronic centre-of-mass frames. Predictions from different Monte Carlo models are compared to the data. The first and second moments of the multiplicity distributions are determined and the KNO scaling behaviour is investigated. The multiplicity distributions as a function of $Q^2$ and the Bjorken variable $x_{\rm Bj}$ are converted to the hadron entropy $S_{\rm hadron}$, and predictions from a quantum entanglement model are tested.
