SO(10) domain-wall brane models
- School of Physics, University of Melbourne, Victoria 3010 (Australia)
We construct domain-wall brane models based on the grand-unification group SO(10), generalizing the SU(5) model of Davies, George, and Volkas. Motivated by the Dvali-Shifman proposal for the dynamical localization of gauge bosons, the SO(10) symmetry is spontaneously broken inside the wall. We present two scenarios: in the first, the unbroken subgroup inside the wall is SU(5)xU(1){sub X}, and in the second it is the left-right symmetry group SU(3)xSU(2){sub L}xSU(2){sub R}xU(1){sub B-L}. In both cases we demonstrate that the phenomenologically-correct fermion zero modes can be localized to the wall, and we briefly discuss how the symmetry-breaking dynamics may be extended to induce breaking to the standard model group with subsequent electroweak breaking. Dynamically localized gravity is realized through the type 2 Randall-Sundrum mechanism.
