摘要

研究了10 GeV神经网络碰撞质心能量下质子-质子和氘核-氘核相互作用的两粒子横向动量（PT）关联。利用Geant4 FTF和Pythia 6.4模型计算了Λ-hyperons和反-Λ-hyperons、K-、π-介子和质子之间的相关性。结果表明，质子-质子相互作用中Λ-hyperons与奇异粒子之间的PT相关性在FTF模型中比在Pythia模型中更强。在NICA SPD实验中可以研究两粒子PT的相关性。对两粒子相关性的研究有助于阐明夸克-胶子弦断裂的机制。

Possible Studies of Two-Particle Transverse Momentum Correlations in Proton–Proton and Deuteron–Deuteron Interactions at NICA Energies

Two-particle transverse momentum (P_T) correlations are investigated for proton–proton and deuteron–deuteron interactions at the center-of-mass energy of NN collisions of 10 GeV. The correlations between Λ-hyperons and anti-Λ-hyperons, K-, π-mesons and protons are calculated using the Geant4 FTF and Pythia 6.4 models. It is shown that P_T correlations between Λ-hyperons and strange particles in proton-proton interactions are stronger in the FTF model than in the Pythia model. Two-particle P_T correlations can be studied at the NICA SPD experiment. Studies of two-particle correlations can help clarify the mechanism of quark–gluon string fragmentation.
