Radiative penguin decays at BABAR.

We report preliminary results based on a data sample of 20.7 fb[sup -1] recorded at the ϒ(4S) resonance by the BABAR detector at the PEP-II energy asymmetric collider at the Stanford Linear Accelerator Center. We have measured the branching fraction B(B[sup 0] → K[sup *]γ) = (4.39 ± 0.41 ± 0.27) × 10[sup -5] and measured a charge asymmetry in the B → K[sup *]γ decays consistent with zero: A[sub CP] = -0.035 ± 0.076 ± 0.012. We also searched for the decay B[sup 0] → γγ and placed the 90% C.L. limit B(B[sup 0] → γγ) < 1.7 × 10[sup -6]. The search for the electroweak penguin decays B → K (*)l[sup +]l[sup -] yielded the limits B(B → Kl[sup +]l[sup -]) < 0.6 × 10[sup -6] and B(B → K[sup *]l[sup +]l[sup -]) < 2.5 × 10[sup -6] at the 90% C.L.
