摘要

通过模拟超高能量（7 TeV）的质子对撞，比较了EPOS4和URQMD 3.4 （LHC）事件发生器的运行结果。证明了EPOS4中重子和轻子电荷守恒定律和能量守恒定律的违反。通过与实验数据的比较，研究了能量守恒和重子、轻子电荷滤波对赝快度范围|η|≤1.5内多重分布的影响。

On the Applicability of the EPOS4 and URQMD (LHC) Generators for the Analysis of 7-TeV pp-Collisions

The results of operation of the EPOS4 and URQMD 3.4 (LHC) event generators were compared by the example of simulation of pp-collisions at ultrahigh energies (7 TeV). Violation of the laws of conservation of baryon and lepton charges and conservation of energy in EPOS4 was shown. A comparison with experimental data was made, and the influence of event filtering by conservation of energy and baryon and lepton charges on the multiplicity distribution in the pseudorapidity range |η| ≤ 1.5 was studied.
