摘要:

纹理矩阵是一种通过Yukawa耦合消除一些条目以识别相关参数来减轻风味物理描述中固有的冗余的方法。在文献中,一个四零织构方案已经成功地描述了费米子质量和混合。然而,正如我们在这项工作中所展示的那样,改善实验约束需要更新这种分析。本文研究了夸克和轻子的2-零织构质量矩阵的含义。我们表明,在每个质量矩阵中引入一个新的参数,使我们能够达到良好的结果,相对较低的成本在可预测性。我们报告了一个数值研究使用杂交自然启发/元胞自动机搜索算法。我们发现轻子和夸克可以用相同的1-零结构来描述。我们描述了一些情况下,可以实现简化的描述,包括参数空间中的一个狭窄的区域,其中相同的值描述带电轻子和中微子,这是一个更强的版本,以前提出的通用纹理约束。

英文摘要:

Texture matrices are a way of mitigating the redundancy inherent in the description of flavor physics via Yukawa couplings by eliminating some entries in order to identify relevant parameters. A four-zero texture scheme has been used in the literature to successfully describe fermion masses and mixing. However, as we show in this work, improving experimental constraints require an update to this analysis. In this paper the implications of a 2-zero texture mass matrix is studied for quarks and leptons. We show that the introduction of a new parameter in each mass matrix allow us to reach good results with relative low cost in predictability. We report a numerical study using a hybridized nature-inspired/cellular automata search algorithm. We find that leptons and quarks can be described by the same 1-zero structure. We describe some scenarios where a simplified description can be achieved, including a narrow region in parameter space where the same values describe charged leptons and neutrinos, which is a stronger version of a previously proposed Universal Texture Constraint.
