摘要：

In this paper, we test the self-consistencies of the standard and the covariant light-front quark model and study the zero-mode issue via the decay constants of pseudoscalar ( P), vector ( V) and axial-vector ( A) mesons, as well as the P→P weak transition form factors. With the traditional type-I correspondence between the manifestly covariant and the light-front approach, the resulting fV as well as fA1 and fA3 obtained with the λ=0 and λ=± polarization states are different from each other, which presents a challenge to the self-consisten...
