本文介绍了Wess-Zumino-Novikov-Witten模型的一种变形,其目标空间为三维压缩球。我们展示了如何与一个适当的选择Wess-Zumino和边界项,它是可能的,以构建一个无限的家庭保守的费用实现SU(2)杨。最后讨论了压缩参数在重整化群流中的作用。
We introduce a deformation of the Wess–Zumino–Novikov–Witten model with three-dimensional squashed sphere target space. We show how with an appropriate choice of Wess–Zumino and boundary terms it is possible to construct an infinite family of conserved charges realizing an SU (2) Yangian. Finally we discuss the running of the squashing parameter under renormalization group flow.
