Possible resolution of the Λ-term problem in an N = 1 supergravity
Krasnikov N. V., Matveev V. A.
A class of superpotentials for which the cosmological Λ term automatically vanishes at the minimum is proposed for an N — 1 supergravity. In this approach the vacuum is degenerate with respect to both the symmetric and asymmetric phases. This circumstance may have some nontrivial consequences for cosmology.
