  In this study, since the doubly heavy baryons masses are experimentally
unknown (except and ), we present the ground state masses and the positive and
negative parity excited state masses of doubly heavy baryons. For this purpose,
we have solved the six-dimensional hyperradial Schr\"odinger equation
analytically for three particles under the hypercentral potential by using the
ansatz approach. In this paper the hypercentral potential is regarded as a
combination of the color Coulomb plus linear confining term and the
six-dimensional harmonic oscillator potential. We also added the first order
correction and the spin-dependent part contains three types of interaction
terms (the spin-spin term, spin-orbit term and tensor term) to the hypercentral
potential. Our obtained masses for the radial excited states and orbital
excited states of , , , , and systems are compared with other theoretical
reports, which could be a beneficial tool for the interpretation of
experimentally unknown doubly heavy baryons spectrum.
