We investigate the exclusive semileptonic and rare D⟶πK decays within the standard model together with the light-front quark model (LFQM) constrained by the variational principle for the QCD-motivated effective Hamiltonian. The form factors are ob

The issue of resulting in the same physical observables with different current components, in particular from the minus current, has been challenging in the light-front quark model (LFQM) even for the computation of the two-point functions such as me

Light-front time-ordered amplitudes are investigated in the virtual scalar meson production process in (1+1) dimensions using the scalar field model extended from the conventional Wick-Cutkosky model. There is only one Compton form factor (CFF) in th

We investigate the transition form factors ${f}_{+}({q}^{2})$ and ${f}_{\ensuremath{-}}({q}^{2})$ [or ${f}_{0}({q}^{2})$] for the exclusive semileptonic $B\ensuremath{\rightarrow}D\ensuremath{\ell}{\ensuremath{\nu}}_{\ensuremath{\ell}}$ ($\ensuremath

We discuss the electroproduction of a pseudoscalar (0-+) meson or a scalar (0++) meson off the scalar target. The most general formulation of the differential cross section for the 0-+ or 0++ meson process involves only one or two hadronic form facto
