摘　　要：Motivated by the recent ATLAS results in terms of the branching ratios B r(t→qγ),we consider the effects of the anomalous t qγcouplings on the radiative B meson decays¯B→X Dγand B→Vγwith V being light vector mesonsρ,ω,ϕand K∗.Comparing with the corresponding experimental measured data,we obtain the constraints on anomalous t qγcouplings.
