Abstract

In this article we study the rare B-meson decay via two on-shell almost-degenerate Majorana Heavy Neutrinos, into two charged leptons and two pseudoscalar mesons (B±→D0ℓ1±ℓ2±π∓). We consider the scenario where the heavy neutrino masses are ∼ 2 GeV and the heavy-light mixing coefficients are | B_ℓ_N| ²∼ 10 ^{- 5}, and evaluate the possibility to measure the CP-asymmetry at Belle II. We present some realistic conditions under which the asymmetry could be detected.
