是否有一个塔的电荷被发现?

Is there a tower of charges to be discovered?

T. Mansson

摘要:

本文研究了N=4 SYM理论的su(2)-扇区的q-变形的高圈可积性。首先,我们构建了一个推广的长程自旋链,它的最低阶描述的非变形膨胀算子。这个广义模型是建立在Temperley-Lieb代数生成器和描述变形的理论,至少有两个循环。在构造模型时,我们要求存在一个交换电荷,这对三个回路阶数的参数提出了强约束。我们还写下了这个模型的五个第一电荷在两个循环的顺序。我们的主要目标是获得一个明确的表达无限数量的交换费用,所有的扩张算子交换。这意味着可整合性。作为实现这一目标的一步,我们在本文中提出了一个通用的本地收费的单圈扩张算子,这恰好是一个发电机的Temperley-Lieb代数的表达。

英文摘要:

We investigate higher loop integrability for a q-deformation of the su(2)-sector of N=4 SYM theory. First we construct a generalisation of the long range spin chain, which for the lowest orders describes the non-deformed dilatation operator. This generalised model is built up from Temperley-Lieb algebra generators and describes the deformed theory to at least two loops. When constructing the model we have demanded the existence of one commuting charge, which puts strong constraints on the parameters to three loop orders. We also write down the five first charges for this model at two loops order. Our main goal is to obtain an explicit expression for an infinite number of commuting charges, all commuting with the dilatation operator. This would imply integrability. As a step towards this goal we present in this paper an expression for a generic local charge of the one-loop dilatation operator, which happens to be a generator of the Temperley-Lieb algebra.
