摘要：

We argue that tachyon-free type I string vacua with supersymmetry breaking in the open sector at the string scale can be interpreted, via Sand T-duality arguments. as metastable vacua of the supersymmetric type I superstring. The dynamics of the process can be partly captured via nucleation of brane-anti-brane pairs out of the non-supersymmetric vacuum and subsequent tachyon condensation. (c) 2007 Elsevier B.V.
