    Research output: Contribution to journalArticlepeer-review


    We construct N = 1 chiral superstrings with spontaneously broken gauge symmetry in four space-time dimensions. These new string solutions are obtained by a generalized coordinate-dependent Z2 orbifold compactification of some non-chiral five-dimensional N = 1 and N = 2 superstrings. The scale of symmetry breaking is arbitrary (at least classically) and it can be chosen hierarchically smaller than the string scale (α′)- 1 2.
