| 英文摘要 | Recently, we discussed the first example of a phenomenologically realistic intersecting D6-brane model. In this model, the gauge symmetry in the hidden sector is U Sp(2)(1) x U Sp(2)(2) x U Sp(2)(3) x U Sp(2)(4). However, we find that the U Sp(2)(1) x U Sp(2)(2) gauge symmetry can be replaced by a U(2)(12) gauge symmetry, and/or the U Sp(2)(3) x U Sp(2)(4) gauge symmetry can be replaced by a U(2)(34) gauge symmetry since the U Sp(2)(2) stacks of D6-branes contribute to the same Ramond - Ramond tadpoles as those of the U( 2) stacks. Thus, there are three non-equivalent variations of the hidden sector, and the corresponding gauge symmetries are U(2)(12) x U Sp(2)(3) x U Sp(2)(4), U(2)(34) x U Sp(2)(1) x U Sp(2)(2) and U(2)(12) x U(2)(34), respectively. Moreover, we study the hidden sector gauge symmetry breaking, discuss how to decouple the additional exotic particles and briefly comment on the phenomenological consequences. |
