Abstract
We present measurements of B⁺ → ρ⁺γ and B⁰ → ρ⁰γ decays using a combined data sample of 772 × 10⁶ BB¯ pairs collected by the Belle experiment and 387 × 10⁶ BB¯ pairs collected by the Belle II experiment in e⁺e⁻ collisions at the ϒ(4S) resonance. After an optimized selection, a simultaneous fit to the Belle and Belle II datasets yields 114 ± 12 B⁺ → ρ⁺γ and 99 ± 12 B⁰ → ρ⁰γ decays...
