Leptoquark-mediated Dirac neutrino mass and its impact on $B\to K\hat{I}½\bar{\hat{I}}½$ and $K\to \ddot{I}€\hat{I}½\bar{\hat{I}}½$ decays

Chuan-Hung Chen, Cheng-Wei Chiang, Leon M. G. de la Vega

Right-handed neutrinos $\hat{I}{½}_R$ play a crucial role in flavor-changing neutral-current processes with missing energy, such as $b\to s + \slashed{E} $ and $d\to s + \slashed{E} $, whe…
