It is estimated with the form factors , and parameter GeV [17] based on the BSW model.
^bIt is estimated with the instantaneous nonrelativistic approximation and the potential model based on the BS equation.
^cIt is estimated in a relativistic model with a one-gluon interaction plus a scalar confinement potential based on the BS equation.
^dIt is estimated with the form factors , using a quasipotential in the relativistic quark model [20].
^eIt is estimated with the form factors , in the nonrelativistic constituent quark model [21, 22].
^fIt is estimated with the form factors (0.571), (0.426) in the light-front quark model based on the Coulomb plus linear (harmonic oscillator) potential, together with the hyperfine interaction [23].
^gIt is estimated with the form factors , in the relativistic independent quark model [24].
