夸克的改进S3模型

Updated S3 Model of Quarks

Ernest Ma, Blazenka Melic

摘要:

更新了2004年提出的一个利用非阿贝尔离散对称性S3来理解夸克和轻子味结构的模型,特别关注夸克和标量扇区。我们展示了这个模型的近似剩余对称性如何解释夸克混合矩阵的模式,以及为什么最近在大型强子对撞机上观察到的126 GeV粒子非常像标准模型中的希格斯玻色子。我们确定了这个模型的标量质量上最强的唯象边界,并预测可能观察到的衰变b -> s τ-μ +,但不是b -> s τ + μ-。

英文摘要:

A model proposed in 2004 using the non-Abelian discrete symmetry S3 for understanding the flavor structure of quarks and leptons is updated, with special focus on the quark and scalar sectors. We show how the approximate residual symmetries of this model explain both the pattern of the quark mixing matrix and why the recently observed particle of 126 GeV at the Large Hadron Collider is so much like the one Higgs boson of the Standard Model. We identify the strongest phenomenological bounds on the scalar masses of this model, and predict a possibly observable decay b -> s tau- mu+, but not b -> s tau+ mu-.
