多重数的胶子模型描述

Multiplicity description by gluon model

E. S. Kokoulina

摘要:

在U-70加速器(IHEP,Protvino)上对质子-质子相互作用中的高多重性事件进行了研究。这些事件极为罕见。通常,蒙特卡罗程序低估了该区域的拓扑截面。提出了胶子优势模型(GDM)来描述它们。它基于QCD和强子化阶段的唯象方案。这个模型表明强子化和胶子裂变的复合机制。SVD合作的未来计划旨在研究一个长期存在的难题,即过量软光子产额及其与杜布纳JINR的U-70和Nuclotron设施的高多重性的联系。

英文摘要:

Study of high multiplicity events in proton-proton interactions is carried out at the U-70 accelerator (IHEP, Protvino). These events are extremely rare. Usually, Monte Carlo codes underestimate topological cross sections in this region. The gluon dominance model (GDM) was offered to describe them. It is based on QCD and a phenomenological scheme of a hadronization stage. This model indicates a recombination mechanism of hadronization and a gluon fission. Future program of the SVD Collaboration is aimed at studying a long-standing puzzle of excess soft photon yield and its connection with high multiplicity at the U-70 and Nuclotron facility at JINR, Dubna.
