Suppressing the Cosmological Constant in Non-Supersymmetric Type I Strings
We construct non-supersymmetric type I string models which correspond to consistent flat-space solutions of all classical equations of motion. Moreover, the one-loop vacuum energy is naturally fixed by the size of compact extra dimensions which, in the two-dimensional case, can be lowered to a fract...
