Cabibbo-allowed charmed meson decays into a pseudoscalar meson and an axial-vector meson are studied. The charm to axial-vector meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise quark model. The dipole momentum dependence of the D→ K transition form factor and the presence of a sizable long-distance W-exchange are the two key ingredients for understanding the data of D→K̅a_1. The K_1A-K_1B mixing angle of the strange axial-vector mesons is found to be ≈±37^∘ or ±58^∘doi:10.1103/physrevd.67.094007 fatcat:4dti4ragpzdenm2u7ugf4pfk7u
