对AdS/CFT的Froissart界的改进
Improvements to the Froissart bound from AdS/CFT
摘要：
在本文中，我们考虑的问题的Froissart限制的高能量行为的总截面。这个界限，最初使用散射振幅的解析性原理导出，被认为是满足所有可用的实验数据的总强子截面。在强耦合，规范/引力对偶已被用来提供一些见解，这种行为。在这项工作中，我们发现的subleading条款，所以派生的Froissart绑定从AdS/CFT。我们发现，一个$(\ln \frac{s}{s_0})$项得到，具有负系数。我们看到，对当前可用数据的拟合证实了由于包含这样一个具有适当符号的项而导致的拟合的改善。
英文摘要：
In this paper we consider the issue of the Froissart bound on the high energy behaviour of total cross sections. This bound, originally derived using principles of analyticity of scattering amplitudes, is seen to be satisfied by all the available experimental data on total hadronic cross sections. At strong coupling, gauge/gravity duality has been used to provide some insights into this behaviour. In this work, we find the subleading terms to the so-derived Froissart bound from AdS/CFT. We find that a $(\ln \frac{s}{s_0})$ term is obtained, with a negative coefficient. We see that the fits to the currently available data confirm improvement in the fits due to the inclusion of such a term, with the appropriate sign.
