场-费曼强子化模型中的关联函数

Correlation function in Field - Feynman hadronization model

L. Grigoryan

摘要:

30年前,Field和Feynman提出了一个非常成功的强子化模型来描述初始夸克喷注中介子的产生。到目前为止,该模型用于实验设计和与实验数据进行比较。在这项工作中,它表明,该模型中的关联函数,作为一个功能的两个最终强子的能量有有趣的性质(能量采取的分数初始夸克能量,并等于$z_{1}$和$z_{2}$,分别)。特别地,对于某些介子对,在变量$z_{2}$(在固定的$z_{1}$值下)上存在运动学区域,在那里它是正的并且出乎意料地大。这些运动学区域的关联函数的实验研究具有双重意义,一方面有助于研究夸克喷注的某些精细性质,另一方面有助于验证模型的物理假设,获得更精确的参数值。

英文摘要:

Very successful hadronization model for the production of mesons in the jets of initial quarks was proposed thirty years ago by Field and Feynman. The model is used so far in the design of experiments and for comparison with the experimental data. In this work it is shown that correlation function in that model, as a function of the energies of two final hadrons has interesting properties (energies are taken in fractions of initial quark energy, and equal $z_{1}$ and $z_{2}$, respectively). In particular, for some pairs of mesons there are kinematic regions over variable $z_{2}$ (at fixed values of $z_{1}$), where it is positive and unexpectedly large. The experimental investigation of the correlation functions in these kinematic regions has twofold interest, from one side it can help to investigate some delicate properties of quark jets and from the other side can help to verify the physical suppositions of model, and to obtain more precise values of parameters.
