We investigate all spherically symmetric fundamental monopole solutions with fixed topological charge in the SU(5)-->[SU(3) x SU(2) x U(1)]/Z(3) x Z(2) symmetry breaking. We find that there are three solutions that are gauge equivalent but, as we argue, would correspond to physically distinct degrees of freedom in the dualized version of the model. The triplication of monopoles could help us understand the observed family structure of standard model particles.
我们研究了在SU(5)→[SU(3)×SU(2)×U(1)]/Z(3)×Z(2)对称性破缺中具有固定拓扑电荷的所有球对称基本单极子解。我们发现有三个规范等价的解，但正如我们所论证的，在模型的对偶版本中它们将对应于物理上不同的自由度。单极子的三重性可能有助于我们理解标准模型粒子所观测到的家族结构。
