论文摘要
我们研究了在$ b \ \ b \ to ssμm$转换中观察到的偏差的后果，用于改变风味的中性流动过程，涉及较低的夸克和中微子。我们在有效的现场理论方法中得出了相关的Wilson系数，该方法涉及SM仪表对称性，包括右手电流，基于近似$ u（2）$对称性的风味结构，并假设只有SM样光中微子。我们讨论了$ b \与k^{（*）}ν\ barν$和$ k \ bar $ k \ toπν\barν$分支比率在线性最小风味的情况下，并且在更一般的框架中，在每种情况下，在每种情况下都强调了各种新物理风景的作用，以解释$ b \ deviations $ b \ deviations。
We investigate the consequences of deviations from the Standard Model observed in $b\to sμμ$ transitions for flavour-changing neutral-current processes involving down-type quarks and neutrinos. We derive the relevant Wilson coefficients within an effective field theory approach respecting the SM gauge symmetry, including right-handed currents, a flavour structure based on approximate $U(2)$ symmetry, and assuming only SM-like light neutrinos. We discuss correlations among $B \to K^{(*)} ν\bar ν$ and $K\to πν\bar ν$ branching ratios in the case of linear Minimal Flavour Violation and in a more general framework, highlighting in each case the role played by various New Physics scenarios proposed to explain $b\to sμμ$ deviations.
