The masses of the ground state heavy baryons are studied using the hypercentral approach. The considered potential is a combination of Coulombic, linear confining and harmonic oscillator terms. An improved form of the hyperfine interaction and isospin dependent quark potential is introduced. By solving the Schrödinger equation for three particles system, we calculate the ground state masses of the baryons containing one, two and three heavy quarks. The obtained results are very close to the ones obtained in experiments or in the other works.

In this work, we study the Hamiltonian of Deuteron as a two-body system and solve the equation of the system in the non-relativistic limit. We obtain the ground state wave function as well as the corresponding energy eigenvalue of the deuteron system. The considered potentials are a combination of the confinement, Coulomb-like (as the one arising from one gluon exchange) and Goldstone boson exchange interaction.
