23 Scopus citations


Dimensionally regularized dispersion theory is used to compute the O(3g3f2) contribution to the charge renormalization function g, where g is a gauge field coupling and f is a quartic (pseudo) scalar selfcoupling. Some motivations for and systematics of the calculation are discussed. Special attention is given to an N=4 globally supersymmetric gauge theory.
