Study of light-cone distribution amplitudes for p-wave heavy mesons

In this paper, a study of light-cone distribution amplitudes for p-wave heavy mesons is presented in both general and heavy quark frameworks. Within the light-front approach, the leading twist light-cone distribution amplitudes, phi(M)(u) and their relevant decay constants of heavy scalar, axial-vector, and tensor mesons, f(M), are formulated. The relations of some decay constants can be simplified when the heavy quark limit is taken into account. After fixing the parameters which appear in a Gaussian wave function, the corresponding decay constants are calculated and compared with those of other theoretical approaches. The curves and the first six xi moments of phi(M)(u) are plotted and estimated. These results all endorse the requirements of heavy quark symmetry.
