摘要:

研究了有效作用量方法在具有胶子辐射的两中心和三中心碰撞中的应用。在诱导顶点的极点奇异点附近的积分规则,使结果与QCD一致。证明了通过引入中间胶子和夸克的标准费曼传播子,振幅可以从纯横向图像恢复。

英文摘要:

Application of the effective action approach to amplitudes with loop integration is studied for collisions on two and three centers with possible gluon emission. A rule is formulated for the integration around pole singularities in the induced vertices which brings the results in agreement with the QCD. It is demonstrated that the amplitudes can be restored from the purely transverse picture by introducing the standard Feynman propagators for intermediate gluons and quarks.
