Atsushi Hinata

摘要:

研究了具有规范$\mathrm{U}(1)_X$味对称性的多重Higgs二重态超对称标准模型。当味对称性被flavon的真空期望值破缺时,称为物质三重性的$\mathbb{Z}_3$对称性$M_3$仍然存在,它禁止了5维算符的重子数破坏。我们研究了额外的Higgs场对味对称性反常抵消的贡献,并分析了包括多代Higgs场以及夸克和轻子的质量谱。我们给出了一系列的$\mathrm{U}(1)_X$电荷分配,再现了夸克和轻子的质量和混合角。我们还发现,与这样的现实的电荷分配,额外的希格斯场获得的质量周围的中间尺度和去耦的电弱物理,因为全纯的超势。

英文摘要:

We study the supersymmetric standard model with multiple Higgs doublets with gauged $\mathrm{U}(1)_X$ flavor symmetry. When the flavor symmetry is broken by the vacuum expectation value of flavon, the $\mathbb{Z}_3$ symmetry $M_3$ called matter triality remains and it prohibits the baryon number violation up to dimension-5 operators. We study the contribution of the extra-Higgs fields to the anomaly cancellation of flavor symmetry and analyze the mass spectra including the multiple generations of Higgs fields as well as quarks and leptons. We show a series of $\mathrm{U}(1)_X$ charge assignments, which reproduce the observed masses and mixing angles of quark and lepton. We also find that, with such realistic charge assignments, the extra-Higgs fields obtain masses around the intermediate scale and decouple from the electroweak physics because of the holomorphy of superpotential.
