摘要

夸克和夸克的偶极矩是 flavor 空间中的矩阵,这些矩阵可能揭示与 mass 矩阵相同的关于 flavor 结构的资料。偶极矩阵的非对角元导致如 μ>eγ\mu -> e \gamma 等的 flavor-changing 衰变,而对角元的虚部则产生电偶极矩。我们分析了夸克偶极矩随夸克质量的比例尺在标准模型之外的理论中。虽然在许多模型中,偶极矩大致随夸克质量成比例,但证明存在简单模型,其中 even 矩按质量的立方比例或以其他方式比例。 presented an explicit example with cubic scaling, which is motivated on independent grounds from large angle neutrino oscillation data. our results have great significance for the observability of the electric dipole moments of e, μ\mu and τ\tau, and the rare decays μ>eγ\mu -> e \gamma, and τ>μγ\tau -> \mu \gamma, and will be tested in several forthcoming experiments。
