高阶弦效应和坡密子的性质

Higher order string effects and the properties of the Pomeron

Dmitri Kharzeev, Edward Shuryak, Ismail Zahed

摘要:

我们在QCD的有效弦论中重新讨论了坡密子的描述。利用弦对偶关系,我们展示了静电势如何映射到表现出坡密子行为的高能散射振幅上。除了Pomeron截距和斜率外,由高阶弦修正产生的新的附加项也影响高能核子的尺寸增长及其在碰撞参量空间中的分布.弦描述也允许只在临界维中消失的奇子。在有效弦描述中出现的一些坡密子的特征可以在未来的EIC对撞机上进行研究。

英文摘要:

We revisit the description of the Pomeron within the effective string theory of QCD. Using a string duality relation, we show how the static potential maps onto the high-energy scattering amplitude that exhibits the Pomeron behavior. Besides the Pomeron intercept and slope, new additional terms stemming from the higher order string corrections are shown to affect both the growth of the nucleon's size at high energies and its profile in impact parameter space. The stringy description also allows for an odderon that only disappears in critical dimension. Some of the Pomeron's features that emerge within the effective string description can be studied at the future EIC collider.
