Is the Chiral Model equivalent to Wess-Zumino-Witten Model when coupled with Gravity?
Shin'ichi Nojiri
Abstract
We investigate the non-abelian T-duality of Wess-Zumino-Witten model. The obtained dual model is equivalent to the model dual to the SU(2) chiral model found by Curtright-Zachos. This might tell that the Wess-Zumino term would be induced when the chiral model couples with gravity.
