An. Kamal et Qp. Xu, INTRODUCING LIGHT VECTOR AND AXIAL-VECTOR MESONS IN THE UNION OF CHIRAL AND HEAVY-QUARK SYMMETRIES, Physical review. D. Particles and fields, 49(3), 1994, pp. 1526-1533
We introduce light vector and axial vector mesons as gauge particles i
n a (broken) local SUL(3)XSU(R)(3) symmetry. We also introduce a heavy
axial vector meson and the interactions that combine chiral and heavy
quark symmetries. Defining the weak current with appropriate chiral t
ransformation properties we calculate the form factors in D-->K, D-->K
, and D-->K-1A transitions. The results are in agreement with data, w
herever data are available.
