| Abstract: | A relativistic quark model based on Dirac equation with the independent-quark confining potential of the form (1 +γ
0)a ln(r/b)] is used to compute the weak electric and magnetic form factors for semileptonic baryonic decays in the electronic decay
modes. The values obtained for (g
2/g
1) agree with the non relativistic results and those for (f
2/f
1) agree with the MIT bag model values of Donoghue and Holstein. The SU(3) symmetry breaking does not generate appreciable
departures in (f
2/f
1) values from corresponding Cabibbo values. |
