Exploring CP-violation, via heavy neutrino oscillations, in rare B meson decays at Belle II

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 ± → D 0 ℓ 1 ± ℓ 2 ± π ∓ ). We consider the scenario where the heavy neutrino masses are ∼ 2 GeV and the heavy-light mixing coefficient...

Description
Summary:	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 ± → D 0 ℓ 1 ± ℓ 2 ± 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.
