Description
We investigate the consequences of deviations from the Standard Model observed in b→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→K(∗)νν and K→πνν branching ratios.
Assuming that NP has a CP-violating phase, we search for the observables which can test it. Then we discuss the correlation of New Physics in D→πll, D→πνν, K→πνν and K→π ll decays.
