Tau and dark sector searches at Belle and Belle II
Abstract
The Belle and Belle II experiments provide a powerful platform for beyond-the-Standard-Model searches, particularly in tau and dark sectors. This summary reports include a measurement of CP violation in τ- → π- KS0 ντ, a search for τ- → ℓ- η, a search for axion-like particles via e+ e- → γa (→ γγ) using Belle II data, and a search for feebly interacting particles in B → h Xinv decays using Belle data.

AB - The Belle and Belle II experiments provide a powerful platform for beyond-the-Standard-Model searches, particularly in tau and dark sectors. This summary reports include a measurement of CP violation in τ^- → π^- K_S^0 ν_τ, a search for τ^- → ℓ^- η, a search for axion-like particles via e^+ e^- → γa (→ γγ) using Belle II data, and a search for feebly interacting particles in B → h X_inv decays using Belle data.
