软强子碰撞中光子辐射的模拟

Modeling photon radiation in soft hadronic collisions

B. Z. Kopeliovich, M. Krelina, I. K. Potashnikova, K. Reygers

摘要:

用碰撞强子的更高Fock态描述了伴随着软光子辐射的多重产生(反)夸克的软强子碰撞,其中也包含光子分量。用夸克-胶子弦模型对Fock态分布函数进行了整形。夸克的光子辐射在色偶极现象学中描述。在宽的光子横动量范围内,计算结果与已有的数据符合得很好。

英文摘要:

Soft hadronic collisions with multiple production of (anti)quarks accompanied with soft photon radiation are described in terms of higher Fock states of the colliding hadrons, which contain a photon component as well. The Fock state distribution functions are shaped with the Quark-Gluon String Model. Photon radiation by quarks is described within the color-dipole phenomenology. The results of calculations are in a good accord with available data in a wide range of transverse momenta of the photons.
