ep碰撞中的排斥衍射和Pomeron轨道

Exclusive diffraction and Pomeron trajectory in ep collisions

S. Fazio

摘要:

在HERA上研究了在很宽的运动学范围内,粒子碰撞中矢量介子和实光子的唯一衍射产生。在这里,我们提出了最新的实验结果与雷吉型模型。通过对HERA的深虚康普顿散射(DVCS)数据的分析,推导出Pomeranchuk轨道(Pomeron),并讨论了它的基本性质,即它的表观“硬度”和它的“非平坦”行为。

英文摘要:

The exclusive diffractive production of vector mesons and real photons in ep collisions has been studied at HERA in a wide kinematic range. Here we present the most recent experimental results together with a Regge-type model. We deduce the Pomeranchuk trajectory (Pomeron) by analyzing the HERA data on deeply virtual Compton scattering (DVCS), and then discuss its basic properties, namely its apparent "hardness" and its "non-flat" behavior, different from the claims of some authors.
