Weak Form Factors for Semileptonic Transitions of Baryons in a Relativistic Potential Model of Independent Quarks

This is the authors' abstract. We don't add key points for this paper.

Weak electric and magnetic form factors for semileptonic transitions of baryons are calculated in a relativistic quark model with the independent quark confining potential of the form [Formula: see text], a > 0. The values obtained for g 2 /g 1 for various decay modes compare well with the nonrelativistic results of Donoghue and Holstein. The values of g 1 /f 1 extracted from our model calculations of f 2 /f 1 in the Cabibbo limit are not very different from those of the experiment. The values calculated for f 2 /f 1 for various semileptonic transitions also agree well with those of the MIT bag model. The SU(3) symmetry breaking does not degenerate appreciable departures in f 2 /f 1 values from the corresponding Cabibbo values.
