Phys. Rev. D 35, 648–654 (1987)On toroidal compactification of heterotic superstringsReceived 18 August 1986; published in the issue dated 15 January 1987 I comment on the use of background gauge fields and antisymmetric tensor fields in toroidal compactification of heterotic strings, and explicitly construct the background gauge field that interpolates between the E8×E8 and Spin(32)/Z2 theories defined on R9×S1. © 1987 The American Physical Society URL:
