Sklyanin图与全重数下的簇邻接

The Sklyanin Bracket and Cluster Adjacency at All Multiplicity

John Golden, Andrew J. McLeod, Marcus Spradlin, Anastasia Volovich

摘要:

我们认为,Gr(4,n)上的Sklyanin Poisson括号可以有效地检验平面${\cal{N}}=4$超对称Yang-Mills理论中的振幅是否满足集团邻接性.我们使用这个测试表明,集群邻接是满足所有的一个和两个循环MHV振幅在这个理论中,一旦适当的调节。使用这种技术,我们还表明,集群邻接意味着在所有粒子多重性的扩展斯坦曼关系。

英文摘要:

We argue that the Sklyanin Poisson bracket on Gr(4,n) can be used to efficiently test whether an amplitude in planar ${\cal{N}}=4$ supersymmetric Yang-Mills theory satisfies cluster adjacency. We use this test to show that cluster adjacency is satisfied by all one- and two-loop MHV amplitudes in this theory, once suitably regulated. Using this technique we also demonstrate that cluster adjacency implies the extended Steinmann relations at all particle multiplicities.
