论文摘要
已使用带电的粒子多样性和横向动量（$ p _ {\ rm t} $）的汇总值估算EPOS3质子 - 质子 - 普罗顿（$ pp $）事件的EPOS3 proton-proton（$ pp $）事件的前进（FB）相关强度，而无需和没有水力的颗粒粒子在中心元素中的颗粒$ \ s $ \ ss sqs sq sq rt and sq sqrt and Sq rt = 7 the 7 the。 FB Windows之间的不同伪型窗口宽度（$δη$）和差距（$η_{gap} $）。我们已经研究了Fb相关强度的变化，$η_{Gap} $，$δη$，$ \ sqrt {s} $，$ p _ {\ rm t} $ cuts and Multilecity类。将结果与相应的爱丽丝和地图集数据进行比较。 EPOS3模型定性地再现了LHC数据相关强度的总体变化。但是，对于$ pp $事件的定量一致性是更好的，该事件使用具有ATLAS数据的EPOS3与颗粒流体动力学演变产生。
Charged-particle multiplicity and summed values of the transverse momentum ($p_{\rm T}$) have been utilized for estimating forward-backward (FB) correlation strength for EPOS3 simulated proton-proton ($pp$) events with and without hydrodynamical evolution of particles at center-of-mass energies $\sqrt{s}$ = 0.9, 2.76, and 7 TeV for different pseudorapidity window width ($δη$) and gap ($η_{gap}$) between the FB windows. We have studied the variation of FB correlation strength with $η_{gap}$, $δη$, $\sqrt{s}$, $p_{\rm T}$ cuts and multiplicity classes. Results are compared with the corresponding ALICE and ATLAS data. EPOS3 model qualitatively reproduces the overall variation of correlation strength of the LHC data. However, quantitative agreement is better for $pp$ events, generated using EPOS3 with hydrodynamical evolution of particles, with ATLAS data.
