摘要：
The generic observable sector gaugino mass in the weakly-coupled heterotic string compactified to four dimensions by the Scherk-Schwarz scheme (together with hidden sector gaugino condensation inducing the super-Higgs effect with a vanishing cosmological constant) is shown to be nonzero at tree level, being of the order of the gravitino mass, module reasonable assumptions regarding the magnitude of the condensate and the Scherk-Schwarz mass parameters.
