We simulate proton–proton interactions to study densities and multiplicities of charged particles at center-of-mass energy, [Formula: see text] TeV in the forward region and compare predictions with experimental findings of LHCb detector. We use different event generators: Sibyll2.3c, EPOS (1.99 and LHC tunes), and DPMJETIII for the simulations. The kinematic region for momentum [Formula: see text], transverse momentum [Formula: see text] and [Formula: see text] in pseudorapidity is kept same as in the LHCb experiment for forward region. Predictions of different models and experimental data are presented and compared as a function of transverse momentum and pseudorapidity.

7 TeV 正向区域中带电粒子密度和多重性的模型预测

我们模拟质子-质子相互作用来研究质心能量下带电粒子的密度和多重性，[公式：见文本] TeV 在前向区域，并将预测与 LHCb 探测器的实验结果进行比较。我们使用不同的事件发生器：Sibyll2.3c、EPOS（1.99 和 LHC 曲调）和 DPMJETIII 进行模拟。动量[公式：见正文]、横向动量[公式：见正文]和[公式：见正文]在伪快速度中的运动学区域与前向区域的 LHCb 实验保持相同。不同模型和实验数据的预测作为横向动量和伪快度的函数被呈现和比较。
