N = 4大色数SYM中Reggeon-Gluon跃迁的影响因子
Impact factors for Reggeon-gluon transition in N = 4 SYM with large number of colours
摘要:
本文计算了具有四个超荷的超对称Yang-Mills理论中大量色数Nc下Reggeon-Gluon跃迁的影响因子。在下一个到领先的顺序的影响因素不是唯一定义的,必须符合BFKL内核和能量尺度。我们得到的影响因子对应的内核和能量演化参数,这是不变的Moebius变换下的动量空间,并表明,它也是Moebius不变的条款考虑在BDS anastomy。
英文摘要:
We calculate impact factors for Reggeon-gluon transition in supersymmetric Yang-Mills theory with four supercharges at large number of colours Nc. In the next-to-leading order impact factors are not uniquely defined and must accord with BFKL kernels and energy scales. We obtain the impact factor corresponding to the kernel and the energy evolution parameter, which is invariant under Moebius transformation in momentum space, and show that it is also Moebius invariant up to terms taken into account in the BDS ansatz.
