Abstract
We report on the recent measurements of electroweak and radiative penguin 𝐵 decays at the Belle II experiment. We use samples of electron-positron collisions collected at the Υ ( 4 𝑆 ) resonance. We present the measurement of the branching fractions of 𝐵 +/ 0 → 𝐾 ∗ ( 892 ) +/ 0 ℓ + ℓ − ( ℓ = 𝑒, 𝜇 ) , 𝐵 +/ 0 → 𝐾 +/ 0 𝐽 / 𝜓 , and 𝐵 +/ 0 → 𝑋 𝑠 𝛾 decays in the data corresponding to 189 fb − 1 of integrated luminosity. We also present a search of 𝐵 + → 𝐾 + 𝜈 ¯ 𝜈 decay in the data corresponding to 63 fb − 1 of integrated luminosity.
