摘要：

A new class of metastable de Sitter vacua is presented and analyzed in N = 1 supergravity and string theory with tunable (infinitesimally small) value of the cosmological constant. They are based on a gauged R-symmetry and the minimal spectrum contains a vector and a linear multiplet of the string dilaton or of a compactification modulus. In the minimum of the scalar potential supersymmetry is broken by an expectation value of both a D- and F-term. (C) 2014 The Authors. Published by Elsevier B.V.
