B -> phi K*,B -> phi Ks与新物理学

B -> phi K*, B -> phi Ks and New Physics

Alakabha Datta, Maxime Imbeault, David London

摘要:

我们考虑了B -> phi K* 衰变中极化之谜的新物理(NP)解。我们注意到,任何这样的解决方案必须重现的数据在B -> φ Ks,其中有不同意的CP-不对称测量的标准模型。我们研究了S/P、V/A和T簇的10个NP算子。我们发现,只要B -> phi Ks表现出大的CP破坏效应,没有一个单一的运营商可以解释在B -> phi K* 和B -> phi Ks的观察。对于2-NP算子解,有四种可能性,都是S/P类型,目前是允许的。我们将讨论在未来区分这些解决方案的方法。只包含V/A算符的模型,例如那些具有超对称性或额外Z'玻色子的模型,不能同时解释B -> phi Ks和B -> phi K* 数据。另一方面,只有S/P算子的双希格斯模型受到青睐。

英文摘要:

We consider the new-physics (NP) solution to the polarization puzzle in B -> phi K* decays. We note that any such solution must reproduce the data in B -> phi Ks, where there are disagreements with the standard model in CP-asymmetry measurements. We examine 10 NP operators, of S/P, V/A and T variety. We find that, as long as B -> phi Ks exhibits large CP-violating effects, no single operator can explain the observations in both B -> phi K* and B -> phi Ks. For 2-NP-operator solutions, there are four possibilities, all of S/P type, which are presently allowed. We discuss ways of distinguishing among these solutions in the future. Models which contain only V/A operators, such as those with supersymmetry or extra Z' bosons, cannot explain both B -> phi Ks and B -> phi K* data. On the other hand, the two-Higgs-doublet model, which has only S/P operators, is favored.}
