Motivated by the recent ATLAS results in terms of the branching ratios Br(t → qγ),we consider the effects of the anomalous tqγ couplings on the radiative B meson decays (B) → XDγ and B → Vγ with V being light vector mesons ρ,ω,φ and K*.Comparing with the corresponding experimental measured data,we obtain the constraints on anomalous tqγcouplings.
