Description: Arbitrary (1,1) and (1.0) two–dimensional non-linear <math>\sigma </math>–models, modified by the addition of coupling terms which explicitly break supersymmetry, are studied. The geometrical meaning of these additional terms is discussed. Supergraph methods, suitably extended to include the case of broken supersymmetry, are set and employed in explicit higher-loop computations to keep track of the effect that the explicit breaking of supersymmetry has on the ultraviolet behaviour of the originally supersymmetric models.
