Exploring Timelike Region of QCD Exclusive Processes in Relativistic Quark Model

Abstract

We investigate the form factors and decay rates of exclusive $0^{-}\to 0^{-}$ semileptonic meson decays using the constituent quark model based on the light-front quantization. Our model is constrained by the variational principle for the linear plus Coulomb interaction motivated by QCD. Our numerical results are in a good agreement with the available experimental data.
