The Fayet-Iliopoulos D-term and its renormalisation in softly-broken supersymmetric theories
I. Jack, D. R. T. Jones, S. Parsons
We consider the renormalisation of the Fayet-Iliopoulos D-term in a softly-broken abelian supersymmetric theory, and calculate the associated beta-function through three loops. We…

T-Duality and Conformal Invariance at Two Loops
S. Parsons
We show that the conformal invariance conditions for a general sigma-model with torsion are invariant under T-duality through two loops.

O(d,d) invariance at two and three loops
I. Jack, S. Parsons
We show that in a two-dimensional sigma-model whose fields only depend on one target space co-ordinate, the O(d,d) invariance of the conformal invariance conditions observed at one…
