Vector and pseudoscalar charm meson radiative decays.

Combining heavy quark effective theory and the chiral Lagrangian approach we investigate radiative decays of pseudoscalar D mesons. We first reanalyse D∗ → Dγ decays within the effective Lagrangian approach using heavy quark spin symmetry, chiral symmetry Lagrangian, but including also the light vector mesons. We then investigate D → V γ decays and calculate the D → K̄∗0γ and D → ργ partial widths and branching ratios.
