高多重性事件中的奇异性产生

Strangeness production in high-multiplicity events

Marat Siddikov, Iván Schmidt

摘要:

本文详细分析了质子-质子碰撞中产生强子的大横动量$p_{T}$运动学中奇异性的产生。利用色偶极框架,我们估计了K介子的产生截面,并证明了$p_{T}$依赖的形状与现有的实验数据是一致的。我们还分析了奇异强子的自归一化产额作为共同产生的强子的多重性的函数,并发现预测与实验数据中看到的快于线性增长。我们的描述在很大程度上是无参数的,并补充了我们以前的研究致力于解释夸克偶素的多重性增强,以及$D$ -和$B$ -介子。

英文摘要:

In this paper we analyze in detail the production of strangeness in proton-proton collisions in the kinematics of large transverse momenta $p_{T}$ of produced hadrons. Using the color dipole framework, we estimated the production cross-sections for kaons, and demonstrated that the shapes of the $p_{T}$-dependence are in agreement with available experimental data. We also analyzed the self-normalized yields of strange hadrons as a function of multiplicity of co-produced hadrons, and found that the predictions are in agreement with the faster-than-linear growth seen in experimental data. Our description is largely parameter-free and complements our previous studies dedicated to the explanation of multiplicity enhancement of quarkonia, as well as $D$- and $B$-mesons.
