Finite Higgs mass without Supersymmetry
NEW JOURNAL OF PHYSICS(2001)
摘要
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) x 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 T-2/Z(2) orbifold, it gives rise to the standard model with two Higgs doublets.
