title = "Search for lepton flavor-violating decay modes B0→ K*0τ±ℓ∓ (ℓ = e, μ) with hadronic B-tagging at Belle and Belle II",
abstract = "We present the results of a search for the charged-lepton-flavor violating decays B0 → K*0τ±ℓ∓, where ℓ∓ is either an electron or a muon. The results are based on 365 fb−1 and 711 fb−1 datasets collected with the Belle II and Belle detectors, respectively. We use an exclusive hadronic B-tagging technique, and search for a signal decay in the system recoiling against a fully reconstructed B meson. We find no evidence for B0 → K*0τ±ℓ∓ decays and set upper limits on the branching fractions in the range of (2.9–6.4)×10−5 at 90\% confidence level.",
