摘要：

在高能量下，弹性强子截面被认为是由真空交换决定的。在主$1/N_c$展开式的首序中，这个交换过程被确定为BFKL { \em Pomeron}或它的强AdS对偶闭弦引力子\cite{Brower:2006ea}。然而，粒子反粒子截面的差异是由所谓的{ \em Odderon}给出的，它携带C = -1量子数，在与奇数个交换胶子的弱耦合中被识别。在这里，我们表明，对偶描述关联这与Neveu-Schwartz（$B_{μν}$）部门的封闭弦论。我们还讨论了强耦合处理在LHC中心衍射Higgs生产的扩展。

英文摘要：

At high energies, elastic hadronic cross sections are believed to be dominated by vacuum exchange. In leading order of the leading $1/N_c$ expansion this exchange process has been identified as the BFKL {\em Pomeron} or its strong AdS dual the closed string graviton \cite{Brower:2006ea}. However difference of particle anti-particle cross sections are given by a so-called {\em Odderon} carrying C = -1 quantum numbers identified in weak coupling with odd numbers of exchanged gluons. Here we show that the dual description associates this with the Neveu-Schwartz ($B_{μν}$) sector of closed string theory. We also discuss the extension of the strong coupling treatment to central diffractive Higgs production at LHC.
