In supergravity models (such as standard superstring constructions) that possess a Heisenberg symmetry, supersymmetry breaking by the inflationary vacuum energy does not lift flat directions at tree level. One-loop corrections give small squared masses that are negative (∼ −g2H2/(4π)2) for all flat directions that do not involve the stop. After inflation… CONTINUE READING
