Abstract: (Springer)

The electromagnetic transitions between ( J (P) =

{\frac{{3}}{{2}}}

(+)and ( J (P) =

{\frac{{1}}{{2}}}

(+)baryons are important decay modes to observe new hadronic states experimentally. For the estimation of these transitions widths, we empl oy a non-relativistic quark potential model description with color Coulomb plus linear confinement potential. Such a description has been employed to compute the ground-state masses and magnetic moments of the single heavy flavor baryons. The magnetic mom ents of the baryons are obtained using the spin-flavor structure of the constituting quark composition of the baryon. Here, we also define an effective constituent mass of the quarks (ecqm) by taking into account the binding effects of the quarks within t he baryon. The radiative transition widths are computed in terms of the magnetic moments of the baryon and the photon energy. Our results are compared with other theoretical models.
