Chiral (1,0) NLSM and Heterotic Strings

Part of the Texts and Monographs in Physics book series (TMP)


In the NLSM approach to the calculation of the bosonic string LEEA (Sect. 6.1) one considers propagation of a single (test) string in the background of its massless modes (described by a 2d NLSM). Quantum consistency of the NLSM implies its 2d conformai invariance. In the case of the NSR string, the non-chiral (1,1) supersymmetric 2d NLSM should be considered along similar lines. As regards the so-called heterotic strings [407, 408], one should deal with a chiral, (1,0) supersymmetric 2d NLSM [321, 409, 410, 411, 412, 413]. We call the (1,0) supersymmetric 2d NLSM heterotic too.
