Abstract: We look for minimal conditions to construct stable Anti de Sitter and de Sitter vacua from type IIB String theory compactification on Kähler manifolds with torsion in the presence of O3-planes. This allows contributions to the scalar potential from the five-form flux and from D5-branes wrapping torsional cycles -interpreted as non-BPS states carrying discrete Z_2 charge and classified by K-theory- which in turn leads to the construction of AdS and dS vacua respectively. We shall discuss some constraints on the configuration as well as possible sources of instabilities.
