夸克-双夸克表象中衍射解离的模拟

Simulation of diffraction dissociation in quark-diquark representation

V. M. Grichine

摘要:

基于强子-核子相互作用的夸克-双夸克表象,提出了一种低质量单衍射解离模型。将核子-π介子系统的质谱与实验数据和其它模型的预测作了比较。在积分截面的Glauber-Gribov模型框架下计算了强子-核单衍射截面。模型的预测与实验数据进行了比较,在强子-核相互作用中产生的次级粒子的不同分布在动量范围31-320 GeV/c。

英文摘要:

A low mass single diffraction dissociation mode based on the quark-diquark representation of hadron-nucleon interaction is proposed. The mass spectra of nucleon-pion system are compared with experimental data and predictions of other models. The hadron-nucleus single-diffraction cross-sections are calculated in the framework of the Glauber-Gribov model for integral cross-sections. The model predictions are compared with experimental data for the different distributions of secondary particles produced in the hadron-nucleus interactions in the momentum range 31-320 GeV/c.
