Measurement of the branching ratios Γ(Ds*+→Ds+π0)/ Γ(Ds*+→Ds+γ) and Γ(D*0→D0π0)/ Γ(D*0→D0γ)
Physical Review D - Particles, Fields, Gravitation and Cosmology 72:9 (2005)
Abstract:
Data samples corresponding to the isospin-violating decay Ds*+→Ds+π0 and the decays Ds*+→Ds+γ, D*0→D0π0 and D*0→D0γ are reconstructed using 90.4 fb-1 of data recorded by the BABAR detector at the PEP-II asymmetric-energy e+e- collider. The following branching ratios are extracted: Γ(Ds*+→Ds+π0)/Γ(Ds*+→Ds+γ)=0. 062±0.005(stat.)±0.006(syst.) and Γ(D*0→D0π0)/ Γ(D*0→D0γ)=1.74±0.02(stat.)±0.13(syst.). Both measurements represent significant improvements over present world averages. © 2005 The American Physical Society.Search for the radiative decay B0→γ

Abstract:
We perform a search for the exclusive radiative decay B0→γ, which is dominated by b̄d annihilation, in a sample of 124×106 BB̄ events collected with the BABAR detector at the PEP-II asymmetric-energy e+e- storage ring at SLAC. No significant signal is seen. We set an upper limit on the branching fraction of B(B0→γ)<8. 5×10-7 at the 90% confidence level. © 2005 The American Physical Society.Performance of the BaBar-DIRC
