We show that the $R_K$ puzzle in LHCb data and the discrepancy in the anomalous magnetic moment of the muon can be simultaneously explained if a 10 MeV mass $Z^\prime$ boson couples to the muon but not the electron, and that clear evidence of the nonstandard matter interactions of neutrinos induced by this coupling may be found at DUNE.
$Z^\prime$ models with less-minimal flavour violation
我们研究了简化的$Z^\prime$模型的现象学与全球$U(2)^3$味对称的夸克部门,打破了唯一的标准模型汤川耦合。这种味对称性,被称为较少的最小味违反,保护$ΔF=2$过程免受危险的大新物理(NP)效应的影响,同时在$b\to s$跃迁中提供了一个自由的复合相,允许解释K介子衰变($ε^\prime/ε$)和强子$B$ -衰变($B\to Kπ$谜题)中额外的直接CP违反的暗示。此外,一旦$Z^\prime$玻色子与轻子的耦合被包括在内,就有可能解决$b\to s \ell^+\ell^-$跃迁中NP(高于5 $\,σ$能级)的有趣线索。考虑到所有的味道观测在一个全球性的适合,我们发现,$ε^\prime/ε$,$B\to Kπ$难题和$b\to s \ell^+\ell^-$数据可以同时解释。在$b\to s \ell^+\ell^-$观测量,特别是$A_8$,大规模的CP违反的预测,这可以在不久的将来进行测试,并解释$B\to Kπ$和$ε^\prime/ε$难题导致的影响,在大型强子对撞机的di-jet尾部,这是不是远低于目前的限制。一旦包含了$b\to s \ell^+\ell^-$,LHC的数据就需要消除双μ子尾,可能是第二个$Z^\prime$。
