我们确定了一类手征模型,其中希格斯标量场的单圈有效势是有限的,没有任何要求的超对称性。它对应的情况下,希格斯场被确定为一个规范场的分量沿着紧化额外的维度。我们提出了一个六维模型,其中规范群为U(3)×U(3),夸克和轻子分别容纳在基本表象和双基本表象中.这个模型可以嵌入到I型弦理论的D-膜结构中,在T2/T2轨道上紧化后,它产生了具有两个希格斯二重态的标准模型。
We identify a class of chiral models where the one-loop effective potential for Higgs scalar fields is finite without any requirement of supersymmetry. It corresponds to the case where the Higgs fields are identified with the components of a gauge field along compactified extra dimensions. We present a six-dimensional model with gauge group U(3)×U(3) and quarks and leptons accommodated in fundamental and bi-fundamental representations. The model can be embedded in a D-brane configuration of type I string theory and, upon compactification on a T2/ℤ2 orbifold, it gives rise to the standard model with two Higgs doublets.
