标准模型之外物理的味物理约束

Flavor Physics Constraints for Physics Beyond the Standard Model

Gino Isidori, Yosef Nir, Gilad Perez

摘要:

在过去的十年中,在实验测量和理论理解风味物理学方面取得了巨大的进展。特别是,在CKM元素的测定的准确性已大大提高,和大量的味道改变中性电流过程,涉及b -> d,b -> s和c -> u过渡,和CP违反不对称性,已被测量。没有新物理学的证据。因此,在高尺度上对新物理学的强约束适用。特别是,在TeV尺度的新物理的风味结构是强烈的约束。我们回顾了这些限制,我们讨论了哪些是未来的前景,以更好地理解物理学的味道结构超越标准模型。

英文摘要:

In the last decade, huge progress in experimentally measuring and theoretically understanding flavor physics has been achieved. In particular, the accuracy in the determination of the CKM elements has been greatly improved, and a large number of flavor changing neutral current processes, involving b -> d, b -> s and c -> u transitions, and of CP violating asymmetries, have been measured. No evidence for new physics has been established. Consequently, strong constraints on new physics at high scale apply. In particular, the flavor structure of new physics at the TeV scale is strongly constrained. We review these constraints and we discuss which are the future prospects to better understand the flavor structure of physics beyond the Standard Model.
