摘要：

We study the topological G(2) and Spin(7) strings at 1-loop. We define new double complexes for supersymmetric NSNS backgrounds of string theory using generalised geometry. The 1-loop partition function then has a target-space interpretation as a particular alternating product of determinants of Laplacians, which we have dubbed the analytic torsion. In the case without flux where these backgrounds have special holonomy, we reproduce the worldsheet calculation of the G(2) string and give a new prediction for the Spin(7) string. We also comment on connections with topological strings on Calabi-Yau and K-3 backgrounds.
