Abstract

We give an estimate of the CC-even B0B0ˉB^0 \bar{B^0} background coming from the radiative decay Υ(4S)→B0Bˉ0γ\Upsilon(4S)\to B^0\bar B^0\gamma at BB-factories. Our result B(Υ(4S)→B0Bˉ0γ)≃3×10−9B(\Upsilon(4S)\to B^0\bar B^0\gamma) \simeq 3 \times 10^{-9} shows that such background could be safely neglected in the analyses of CPCP violating effects.
