Abstract
Higher-winding-number solutions of the nonlinear σ field are used to break the global as well as local symmetry of SU(2) in a six-dimensional gravity theory coupled with the U(1) Maxwell and σ field. The masses of three gauge bosons are split and their ratios of masses are obtained for various winding numbers. The low-lying states of this model not of Planck scale are a scalar triplet, the graviton, photon, and low-mass gauge bosons.
