The three-body decay B⁰(Bₛ)→ γνν can occur via penguin and box diagrams in the standard model (SM). These channels are useful to determine the decay constants fB (fBₛ) and B (Bₛ) meson wave function. Using the B meson wave function determined in hadronic B (Bₛ) decays, we calculate and get the branching ratio of order 10⁻⁹ and 10⁻⁸ for B⁰ and Bₛ decay, respectively. They agree with previous calculations.
