摘要：

The distance between BPS branes in string theory corresponds to a. at direction in the effective potential. Small deviations from supersymmetry may lead to a small uplifting of this. at direction and to brane inflation. However, this scenario can work only if the BPS properties of the branes and the corresponding flatness of the inflaton potential are preserved in the stable volume compactification. We present an 'inflaton trench' mechanism that keeps the inflaton potential. at due to shift symmetry, which is related to near BPS symmetry in our model.
