重Majorana中微子在$B$衰变中的轻子数破坏

Lepton number violation by heavy Majorana neutrino in $B$ decays

Takehiko Asaka, Hiroyuki Ishida

摘要:

在具有跷跷板机制的模型中,除了普通的活动中微子外,还预测了重Majorana中微子。我们研究了由GeV质量的重中微子$N$引起的$B$衰变中的轻子数破坏。特别地,我们考虑了衰变道$B^+ \to μ^+ \, N \to μ^+ μ^+ π^-$,并通过Belle II的未来搜索实验和未来圆形对撞机(FCC-ee)的$e^+ e^-$碰撞实验导出了混合角$Θ_μ$的灵敏度极限。

英文摘要:

Heavy Majorana neutrinos are predicted in addition to ordinary active neutrinos in the models with the seesaw mechanism. We investigate the lepton number violation (LNV) in $B$ decays induced by such a heavy neutrino $N$ with GeV-scale mass. Especially, we consider the decay channel $B^+ \to μ^+ \, N \to μ^+ μ^+ π^-$ and derive the sensitivity limits on the mixing angle $Θ_μ$ by the future search experiments at Belle II and in $e^+ e^-$ collisions at the Future Circular Collider (FCC-ee).
