大统一风味物理学

Grand Unified Flavour Physics

Susanne Westhoff

摘要:

我们探讨了超对称SO(10)大统一理论中下夸克和轻子的统一。大的大气中微子混合角诱导bR-sR跃迁,这可以解释在Bs-Bsbar混合中测量到的相当大的CP相位。从高维Yukawa项对下夸克轻子统一的修正也将中微子混合转化为sR-dR和bR-dR流。我们发现汤川修正的味结构受到ε K的强烈约束。

英文摘要:

We probe the unification of down quarks and leptons in a supersymmetric SO(10) GUT. The large atmospheric neutrino mixing angle induces bR-sR transitions, which can account for the sizeable CP phase measured in Bs-Bsbar mixing. Corrections to down-quark-lepton unification from higher-dimensional Yukawa terms translate neutrino mixing also into sR-dR and bR-dR currents. We find the flavour structure of Yukawa corrections to be strongly constrained by epsilonK.
