Killing scalar of non-linear sigma models on G/H realizing the classical exchange algebra
arXiv:1405.4638 · doi:10.1016/j.physletb.2014.08.048
Abstract
The Poisson brackets for non-linear sigma models on G/H are set up on the light-like plane. A quantity which transforms irreducibly by the Killing vectors, called Killing scalar, is constructed in an arbitrary representation of G. It is shown to satisfy the classical exchange algebra.
