论文摘要
我们指出了COON振幅$ \ unicode的一些常见定性特征{x2014} $与对数regge轨迹的委内斯振幅的变形家族$ \ Unicode {x2014} $以及用于d-Brane in Ad d-Brane in ads d-Brane in Ads in d d-Brane in dy d-brane in d d-Brane in ads in d d-brane in ads in d d-brane in d d-brane in ads in ads in ads in d d-brane in s ads in ads in d d-brane in s ads in d d-brane in。两者都在相对较低的能量下降低到委内兹亚诺振幅。两种系统在其频谱中都有一个积累点,无限数量的状态低于一定能量。到这一点的方法非常相似。两者都具有相同的高能固定角度行为。然而,我们发现在具有最高角动量的状态范围内有一些差异。这些相似之处表明,可能存在一种实现库恩幅度的字符串背景。
We point out some common qualitative features of the Coon amplitude$\unicode{x2014}$a family of deformations of the Veneziano amplitude with logarithmic Regge trajectories$\unicode{x2014}$and the open string scattering amplitude for strings ending on a D-brane in AdS. Both reduce to the Veneziano amplitude at relatively low energies. Both systems have an accumulation point in their spectrum, with an infinite number of states below a certain energy. The approach to this point is very similar. Both have the same high-energy fixed-angle behavior. Nevertheless, we find some differences in the spectrum of states with highest angular momentum. These similarities suggest that there may exist a string background that realizes the Coon amplitude.
