摘要

We prove that the S U ( 3 ) C ? S U ( 2 ) L ? S U ( 3 ) R ? U ( 1 ) X (3-2-3-1) gauge model always contains a matter parity W P = ( ? 1 ) 3 ( B ? L ) + 2 s as conserved residual gauge symmetry, where B ? L = 2 ( β T 8 R + X ) is a S U ( 3 ) R ? U ( 1 ) X charge. Due to the non-Abelian nature of B ? L , the W -odd and W -even fields are actually unified in gauge multiplets. We investigate two viable versions for dark matter according to β = ± 1 / 3 , where the dark matter candidates can be fermion, scalar, or vector fields. We figure out the parameter spaces in the allowed regions of the relic density and direct detection cross sections. Additionally, we examine the neutrino masses induced by the seesaw mechanism along with associated lepton flavor violation processes. The new gauge boson searches at the LEPII and LHC are discussed.

U(1)X电荷。由于B的非阿贝尔性质。 L,W-奇数和W-偶数字段实际上是在标度多重峰中统一的。我们根据β=±1/3研究暗物质的两个可行版本,其中暗物质候选对象可以是费米子,标量或矢量场。我们计算出文物密度和直接检测横截面的允许区域中的参数空间。此外,我们检查了由跷跷板机制以及相关的轻子味道违规过程引起的中微子质量。讨论了在LEPII和LHC上新的规范玻色子搜索。
