Masses of heavy Baryons in a chiral-diquark picture

The baryon magnetic moment is a fundamental observable as its mass which encodes information of the underlying quark-gluon structure and dynamics. Assuming a conventional correlated perturbative chiral quark model (CPχQM). we suggest that the bottombed and charmede singly – doubly heavy baryons are a bound state of two light - heavy diquarks and a single heavy – light antiquark, the spatially wave function of these diquarks has a P- wave and an S-wave in angular momentum in the first and second version of our model respectively, as the result of these considerations we construct the orbital - flavor - spin symmetry of contribution of quarks.we study singly- doubly heavy - flavor baryons using the diquark approach in the framework of the non-relativistic quark model. Considering two different confining potentials as orbital and radial exciting energies between heavy quark and light diquark center of mass in singly heavy baryons or light quark and heavy diquark center of mass in doubly heavy baryons. Also we consider hyperfine interactions between quarks in each diquark. Then we calculate their magnetic moments in our model.The obtained results are in good agreement with experimental data and those of other works.
