Feasibility Study of Lepton Number Violation in Rare $B$ and $K$ Meson Decays

Motoi Endo, Kåre Fridell, Sho Iwamoto +2

We study lepton-number-violating interactions at dimension seven in the Standard Model effective field theory that contribute to the meson decays $B\to K\nu \nu$ and $K\to \pi \nu \nu$. Such…
