AI总结:

研究在RHIC能量下的质子-质子碰撞中观测到奇异数增强,表明脱 confinement 相变已发生。

摘要:

奇异数增强被认为是夸克胶子等离子体(QGP)相变的潜在信号。本文声称在RHIC能量下的质子-质子碰撞中观测到奇异数增强,表明脱 confinement 相变已发生。对物质相变和奇异数产生动力学的深入研究已针对K_s^+(u\bar{s})和K_s^-(s\bar{u})介子、Λ^0(uds)重子以及多奇异数重子Ξ^0(uss)、Ξ^-(dss)和Ω^-(sss)的产生进行了研究。对奇异数和多奇异数强子产生数据集的分析在\sqrt{s} = 200 GeV时进行,如PYTHIA 8事件生成器模拟所报告。我们对高乘积性和低乘积性事件的奇异数和多奇异数强子的横向动量分布进行了研究。在RHIC能量和质子-质子碰撞中,奇异数含量产率随事件乘积性增加而增加。

英文摘要:

Strangeness enhancement is considered as a potential signature for QGP phase transition. Here we claim the observation of strangeness enhancement in proton-proton (pp) collisions at RHIC energy saying the de-confinement phase is reached. The deep study of matter phase transitions and dynamics of strangeness creation has been preformed for $K_{s}^{+}(u\bar{s})$ and $K_{s}^{-}(s\bar{u})$ mesons, $Λ^{0}(uds)$ baryon and for multi-strange baryons $Ξ^{0}(uss)$, $Ξ^{-}(dss)$ and $Ω^{-}(sss)$ production. The analysis of datasets for the strange and multi-strange hadrons production is presented at $\sqrt{s} =$ 200 GeV as reported by the PYTHIA 8 event generator simulations. We preform the transverse momentum distributions of the strange and multi-strange hadrons for high and low multiplicity events. At the RHIC energy and for pp collisions, the strangeness content yield increases with the event multiplicity.
