We address the problem of ambiguity of a function determined by an asymptotic perturbation
expansion. Using a modified form of the Watson lemma recently proved elsewhere, we discuss a
large class of...
Higher Loop Spin Field Correlators in Various Dimensions
Higher Loop Spin Field Correlators Various Dimensions
2010/12/23
We compute higher-point superstring correlators involving spin fields in various even space-time dimensions D at tree-level and to arbitrary loop order. This generalizes previous work in D=4 space-ti...
