论文摘要
最近开发的量子机械字符串+$ {}^3p_0 $偏振夸克碎片的模型与伪级和矢量梅森的生产已在独立的蒙特卡洛计划中实现。该模拟可以详细研究碎裂过程中的夸克自旋依赖性效应，例如横向自旋不对称。特别是，它允许研究媒介膜的产生和衰减对观察到的had子的柯林斯和二脑子不对称的影响，并研究矢量膜的柯林斯效应仍然未知的collins效应。总结了到目前为止获得的蒙特卡洛模拟的主要结果，并与现有的有关SIDIS的实验数据和$ E^+e^ - $ nihihitation的实验数据进行了比较。
The recently developed quantum mechanical string+${}^3P_0$ model of polarized quark fragmentation with pseudoscalar and vector meson production has been implemented in a stand alone Monte Carlo program. The simulation enables the detailed study of the quark spin dependent effects in the fragmentation process such as the transverse spin asymmetries. In particular, it allows to investigate the effects of the production and decay of vector mesons on the Collins and dihadron asymmetries of the observed hadrons, and to study the still unknown Collins effect for vector mesons. The main results of the Monte Carlo simulations obtained so far are summarized and the comparison with the existing experimental data on SIDIS and $e^+e^-$ annihilation to hadrons processes are presented.
