AdS空间中的Pomeron动力学和小x时强子的结构函数

Pomeron dynamics in the AdS space and structure functions of hadrons at small x

Akira Watanabe, Katsuhiko Suzuki

摘要:

在全息量子色动力学的框架下,研究了小x处的Pomeron动力学。小x DIS过程被假设为AdS空间中外部矢量流与强子之间的引力子交换。我们对$F_2^p$、$F_2^π$以及纵向对应物$F_L^p$的计算与实验数据一致。在我们的方法中,我们讨论了$F_2$和$F_L$之间差异的起源。

英文摘要:

The Pomeron dynamics is investigated via deep inelastic scattering (DIS) at small x in the framework of holographic quantum chromodynamics. The small x DIS process is assumed to be described by the graviton exchange between external vector current and hadron in the AdS space. Our calculations for $F_2^p$, $F_2^π$, as well as the longitudinal counterpart $F_L^p$ are consistent with the experimental data. We discuss origins of a difference between $F_2$ and $F_L$ in our approach.
