论文摘要
我们研究了具有多个Higgs Doublets的超对称标准模型，并使用测量$ \ MATHRM {u}（1）_x $风味对称性。当Flavon的真空期望值打破了风味对称性时，$ \ Mathbb {z} _3 $对称$ M_3 $称为Matter Triality剩余，并且禁止Baryon违反dimension-5运算符。我们研究了希格斯领域对取消风味对称性异常的贡献，并分析了质谱，包括希格斯田的多代以及夸克和叶子。我们展示了一系列$ \ mathrm {u}（1）_x $收费分配，该分配复制了观察到的质量和夸克和Lepton的混合角度。我们还发现，通过这种逼真的电荷分配，由于超电势的全体状态，额外的higgs场在中间尺度周围获得了质量，并从电子物理学中脱离了质量。
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.
