N2 - We study the radiative leptonic D meson decays of D(s)/+ → l+υlγ (l = e, μ, τ), D0 → νν̄γ and D0 → l+l-γ (l = e, μ) within the light front quark model. In the standard model, we find that the decay branching ratios of D(s)/+ → e + νeγ, D(s)/+ → μ+νμγ and D(s)/+ → τ+ντγ are 6.9 × 10-6 (7.7 × 10-5), 2.5 × 10-5 (2.6 × 10-4), and 6.0 × 10-6 (3.2 × 10-4), and that of D 0 → l+l-gamma; (l = e, μ) and D0 → νν̄γ are 6.3 × 10-11 and 2.7 × 10-16, respectively.
