(on behalf of the BABAR Collaboration) We report recent results in the search for the rare B meson decays B → ργ and B0 → pi0pi0. These results are based on 56.4 fb−1 collected by the BaBar Collaboration at the SLAC PEP-II e+e − B Factory. We set new 90 % confidence level upper limits B(B0 → ρ0γ) &lt; 1.5 × 10−6, B(B+ → ρ+γ) &lt; 2.8 × 10−6, and B(B0 → pi0pi0) &lt; 3.4 × 10−6.
