The Fayet-Iliopoulos term in Type-I string theory and m-theory

PHYS LETT B 437:3-4 (1998) 318-324

Abstract:

The magnitude of the Fayet-Iliopoulos term is calculated for compactifications of Type-I string theory and Horava-Witten M-theory in which then exists a pseudo-anomalous U(1)(x). Contrary to various conjectures, it is found that in leading order in the perturbative expansion around the weakly-coupled M-theory or Type-I limits, a result identical to that of the weakly-coupled E-8 x E-8 heterotic string is obtained. The result is independent of the values chosen for the Type-I string scale or the size of the M-theory 11th dimension, only depending upon Newton's constant and the unified gauge coupling.
