用Clifford代数方法研究手征对称性破缺和费米子质量谱

A Clifford Algebra Approach to Chiral Symmetry Breaking and Fermion Mass Hierarchies

Wei Lu

摘要:

我们提出了一个Clifford代数的方法来研究复合希格斯玻色子玻色子背景下的手征对称性破缺和费米子质量等级。标准模型费米子由六维二元Clifford代数的代数旋量表示,而三元Clifford代数相关的味投影算子控制允许的味混合相互作用。顶夸克、τ中微子和τ轻子凝聚产生了三种复合电弱希格斯玻色子玻色子。这三种凝聚中的每一种都产生四种不同质量的费米子。这三个群中的费米子质量等级由四费米子凝聚决定,这打破了两个全局手征对称性。四费米子凝聚诱导出类轴子的赝Nambu-Goldstone玻色子,可以作为暗物质的候选者。除了在大型强子对撞机上观测到的125 GeV的希格斯玻色子玻色子外,我们还期望通过粲夸克衰变通道探测到τ中微子复合物希格斯玻色子玻色子。

英文摘要:

We propose a Clifford algebra approach to chiral symmetry breaking and fermion mass hierarchies in the context of composite Higgs bosons. Standard model fermions are represented by algebraic spinors of six-dimensional binary Clifford algebra, while ternary Clifford algebra-related flavor projection operators control allowable flavor-mixing interactions. There are three composite electroweak Higgs bosons resulted from top quark, tau neutrino, and tau lepton condensations. Each of the three condensations gives rise to masses of four different fermions. The fermion mass hierarchies within these three groups are determined by four-fermion condensations, which break two global chiral symmetries. The four-fermion condensations induce axion-like pseudo-Nambu-Goldstone bosons and can be dark matter candidates. In addition to the 125 GeV Higgs boson observed at the Large Hadron Collider, we anticipate detection of tau neutrino composite Higgs boson via the charm quark decay channel.
