【 摘 要 】

The nature of neutrino masses is one of many questions opened about the Standard Model (SM) of elementary particles. The existence of lepton number violating processes, where it changes by two units implies the presence of a (heavy) Majorana neutrino. High precision measurements are essential to this kind of searches. In the B factory experiment Belle II is possible to find these kind of processes, we implemented the simulation and reconstruction of τ-→ π+μ-μ-μτusing belle2 software bas2f to investigate the feasibility of this channel.
