雷吉极限中的对偶共形不变性

Dual conformal invariance in the Regge limit

Cesar Gomez, Johan Gunnesson, Agustin Sabio Vera

摘要:

在QCD的Regge极限中,我们发现了一种对偶共形对称性,它类似于N=4的超杨-米尔斯理论的散射振幅所观察到的对偶共形对称性.结合该理论最初的二维共形对称性,这种对偶对称性可以解释BFKL哈密顿量的可积性。我们还提供证据表明,对称性生存时的一个子集的么正性校正被考虑到通过简要研究非平面的2到m reggeon过渡顶点。

英文摘要:

A dual conformal symmetry, analogous to the dual conformal symmetry observed for the scattering amplitudes of N=4 Super Yang-Mills theory, is identified in the Regge limit of QCD. Combined with the original two-dimensional conformal symmetry of the theory, this dual symmetry can potentially explain the integrability of the BFKL Hamiltonian. We also give evidence that the symmetry survives when a subset of unitarity corrections are taken into account by studying briefly the non-planar 2 to m reggeon transition vertices.
