B -> K π难题与超对称性中CP破坏的新来源

B -> K pi Puzzle and New Sources of CP Violation in Supersymmetry

S. Khalil, A. Masiero, H. Murayama

摘要:

$B^0 \to K^+ π^-$和$B^+ \to K^+ π^0$衰变的CP不对称性之间的差异最近已被证实,其证据大于$5σ$的证据。我们讨论它作为一个可能的信号,新的物理与新的(大)CP破坏的电弱企鹅的贡献。我们提出了一个超对称破缺方案,这种新的CP破坏的来源发生在味非通用三线性标量耦合。

英文摘要:

The difference between the CP asymmetries of the $B^0 \to K^+ π^-$ and $B^+ \to K^+ π^0$ decays has been recently confirmed with an evidence larger than $5σ$'s. We discuss it as a possible signal of new physics associated with new (large) CP violation in the electroweak penguin contributions. We propose a supersymmetry breaking scheme where such new sources of CP violation occur in the flavor non-universal trilinear scalar couplings.
