摘要：
We find that the conjectured heterotic SO(32) five-brane sigma model develops necessarily k-anomalies, and we investigate their form. We show that these anomalies can be absorbed by modifications of the superspace constraints, that satisfy automatically the modified Bianchi-identity dH(7) = X-8 of N = 1, D = 10 supergravity. The k-anomalies induce in particular a quantum deformation of the torsion constraint T-alpha beta(a) = 2 gamma(a)(alpha beta). (c) 2010 Elsevier B.V. All rights reserved.
