Abstract

En 中文
This article is based on the result obtained in hep-th/0508126 and hep-th/0605080 where we use the IIB light-cone string field theory proposed by Dobashi and Yoneya to compute the one string-loop correction to the energies of two impurity BMN states. We found that the result agrees with the gauge theory prediction at leading order-one-loop in Yang-Mills theory-and that is quite close also at second order in Yang-Mills loops. We furthermore find that the half integer powers in the t'Hooft coupling are absent up to the 7/2 power. (C) 2007 WILEY-VCH Verla, GmbH & Co. KGaA, Weinheim.
