abstract
The phenomenon of neutrino flavor oscillations motivates searches for sterile neutrinos in a broad range of masses and mixing-parameter values. A sterile neutrino $N$ that mixes predominantly with the $\tau$ neutrino is particularly challenging experimentally. To address this challenge, we propose a new method to search for a $\nu_\tau$-mixing with $N$ lighter than the $\tau$ lepton. The method uses the large $e^+e^-\to\tau^+\tau^-$ samples collected at $B$-factory experiments to produce the $N$ in $\tau$-lepton decays. We exploit the long lifetime of a sterile neutrino in this mass range to suppress background and apply kinematic and vertexing constraints that enable measuring the sterile neutrino mass. Estimates for the sensitivities of the BaBar, Belle, and Belle~II experiments are calculated and presented.

A comprehensive study of ALPs from $B$-decays
The paper derives the complete two-loop flavor-changing coupling of axion-like particles to b and s quarks and uses it to set updated limits on f_a in KSVZ, DFSZ and Flaxion models.
