QCD中威尔逊圈与散射振幅对偶的实现

Implementation of the Duality between Wilson loops and Scattering Amplitudes in QCD

Yuri Makeenko, Poul Olesen

摘要:

我们将现代关于${\cal N}$ =4 SYM中威尔逊圈和散射振幅之间对偶性的观点推广到大N(或猝灭)QCD中。当夸克质量小或粒子数大时,在高能和动量转移固定的情况下,渐近大的威尔逊圈的面积律行为与散射振幅的Regge-Veneziano行为是对偶的.我们详细阐述了平坦空间中弦论的这种对偶性,确定了大N QCD的盘振幅和威尔逊圈的渐近线。

英文摘要:

We generalize modern ideas about the duality between Wilson loops and scattering amplitudes in ${\cal N}$=4 SYM to large-N (or quenched) QCD. We show that the area-law behavior of asymptotically large Wilson loops is dual to the Regge-Veneziano behavior of scattering amplitudes at high energies and fixed momentum transfer, when quark mass is small and/or the number of particles is large. We elaborate on this duality for string theory in a flat space, identifying the asymptotes of the disk amplitude and the Wilson loop of large-N QCD.
