Leptoquark-mediated Dirac neutrino mass and its impact on B → Kν ν ¯ $$ B\to K\nu \overline{\nu} $$ and K → πν ν ¯ $$ K\to \pi \nu \overline{\nu} $$ decays

Abstract Right-handed neutrinos ν R play a crucial role in flavor-changing neutral-current processes with missing energy, such as and , where Belle-II reports unexpectedly large branching fraction in B → Kν ν ¯ $$ B\to K\nu \overline{\nu} $$ decays. Assuming ν R is the partner of the active neutrino...
