On heterotic vacua with fermionic expectation values
On heterotic vacua with fermionic expectation values
We study heterotic backgrounds with nonātrivial H āflux and nonāvanishing expectation values of fermionic bilinears, often referred to as gaugino condensates. The gaugini appear in the low energy action via the gaugeāinvariant threeāform bilinear . For CalabiāYau compactifications to four dimensions, the gaugino condensate corresponds to an internal threeāform that ā¦
