    We report a search for the charged-lepton flavor violation in Υ(2S) →ℓ∓τ±(ℓ=e, μ) decays using a 25 fb−1Υ(2S) sample collected by the Belle detector at the KEKBe+e−asymmetric-energy collider. We find no evidence for a signal and set upper limits on the branching fractions ($$ \mathcal{B} $$B) at 90% confidence level. We obtain the most stringent upper limits:$$ \mathcal{B} $$B(Υ(2S)→ μ∓τ±)<0.23×10−6and$$ \mathcal{B} $$B(Υ(2S)→ e∓τ±)<1.12×10−6.

    We measure the branching fraction of the decayB−→D0ρ(770)−using data collected with the Belle II detector. The data contain 387 millionBB¯pairs produced ine+e−collisions at theϒ(4S)resonance. We reconstruct8360±180decays from an analysis of the distributions of theB−energy and theρ(770)−helicity angle. We determine the branching fraction to be(0.939±0.021(stat)±0.050(syst))%, in agreement with previous results. Our measurement improves the relative precision of the world average by more than a factor of two.
