Exploring CP-violating heavy neutrino oscillations in rare tau decays at Belle II
In this work, we study the lepton number violating tau decays via two intermediate on-shell Majorana neutrinos Nj into two charged pions and a charged lepton τ±→π±Nj→π±π±ℓ∓. We consider the scenario where the heavy neutrino masses are within 0.5 GeV≤MN≤1.5 GeV. We evaluated the possibility to measur...
