摘要：
We study the transition form factors of the pesudoscalar mesons (pi, eta, and eta') as functions of the momentum transfer Q(2) within the light-front quark model. We compare our results with the recent experimental data by CELLO, CLEO, BaBar and Belle collaborations. By considering the possible uncertainties from the quark masses, we illustrate that our predicted form factors can fit with all the data, including those at the large Q(2) regions.
