Orbifold GUT中的CP破坏和风味混合

CP Violation and Flavour Mixings in Orbifold GUTs

Gautam Bhattacharyya, Gustavo C. Branco, Joaquim I. Silva-Marcos

摘要:

我们将汤川耦合的普遍强度的假设的框架内的一个5D大统一组织模型紧化的$S^1/(Z_2 \times Z_2^{\prime})$ orbifold的味道问题。我们表明,一个定量成功的费米子质量和混合的图片出现从几何起源和汤川矩阵的相位的批量抑制因子之间的相互作用。我们给出了一个明确的例子,其中我们获得了CKM和PMNS矩阵的良好拟合。

英文摘要:

We address the flavour problem by incorporating the hypothesis of universal strength of Yukawa couplings in the framework of a 5D GUT model compactified on an $S^1/(Z_2 \times Z_2^{\prime})$ orbifold. We show that a quantitatively successful picture of fermion masses and mixings emerges from the interplay between the bulk suppression factors of geometric origin and the phases of the Yukawa matrices. We give an explicit example, where we obtain a good fit for both the CKM and PMNS matrices.
