Search for Lepton-Flavor-Violating $τ$ Decays to a Lepton and an Invisible Boson at Belle II
I. Adachi, K. Adamczyk, L. Aggarwal, H. Ahmed et autres
We search for lepton-flavor-violating $τ^-\to e^-α$ and $τ^-\toμ^-α$ decays, where $α$ is an invisible spin-0 boson. The search uses electron-positron collisions at $10.58$ GeV center-of-mass energy with an integrated luminosity of $62.8$ fb$^{-1}$, produced by the SuperKEKB collider and collected with the …
