Abstract

Utilizing the idea of extra large dimensions, it has been suggested that the\ngauge and gravity couplings unification can happen at a scale as low as 1 TeV.\nIn this paper, we explore this phenomenological possibility within string\ntheory. In particular, we discuss how the proton decay bound can be satisfied\nin Type I string theory. The string picture also suggests different scenarios\nof gauge and gravitational couplings unification. The various scenarios are\nexplicitly illustrated with a specific 4-dimensional N=1 supersymmetric chiral\nType I string model with Pati-Salam-like gauge symmetry. We point out certain\nfeatures that should be generic in other Type I strings.\n
