We consider the scenario where the heavy neutrino masses are ∼ 2 GeV and the heavy-light mixing coefficients are | BℓN| 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. © 2020, The Author(s).enArtículo
