摘要：
We introduce an N = 8 supersymmetric extension of the Bogomolny-type model for Yang-Mills-Higgs fields in 2 + 1 dimensions related with twistor string theory. It is shown that this model is equivalent to an N = 8 supersymmetric U(n) chiral model in 2 + 1 dimensions with a Wess-Zumino-Witten-type term. Further reduction to 1 + 1 dimensions yields N = (8, 8) supersymmetric extensions of the standard U(n) chiral model and Grassmannian sigma models. (c) 2007 Elsevier B.V. All rights reserved.
