Search for the Radiative Decays B→ργ and B[superscript 0]→ωγ
A search of the exclusive radiative decays B→ρ(770)γ and B[superscript 0]→ω(782)γ is performed on a sample of about 84×10[superscript 6] BB̅ events collected by the BABAR detector at the SLAC PEP-II asymmetric-energy e[superscript +]e[superscript -] storage ring.

| description | A search of the exclusive radiative decays B→ρ(770)γ and B[superscript 0]→ω(782)γ is performed on a sample of about 84×10[superscript 6] BB̅ events collected by the BABAR detector at the SLAC PEP-II asymmetric-energy e[superscript +]e[superscript -] storage ring. No significant signal is seen in any of the channels. We set upper limits on the branching fractions B of B(B[superscript 0]→ρ[superscript 0]γ)<1.2×10[superscript -6], B(B[superscript +]→ρ[superscript +]γ)<2.1×10[superscript -6], and B(B[superscript 0]→ωγ)<1.0×10[superscript -6] at 90% confidence level (C.L.). Using the assumption that Γ(B→ργ)=Γ(B[superscript +]→ρ[superscript +]γ)=2×Γ(B[superscript 0]→ρ[superscript 0]γ), we find the combined limit B(B→ργ)<1.9×10[superscript -6], corresponding to B(B→ργ)/B(B→K[superscript *]γ)<0.047 at 90% C.L. |
