A new approach for triply heavy Ωccc and Ωbbb baryons spectroscopy in the nonrelativistic quark model

Triply heavy Ω ccc and Ω bbb baryons are studied in the framework of the nonrelativistic quark model based on the ansatz approach in hypercentral constituent quark model. The masses of the ground and excited states of the Ω ccc and Ω bbb baryons are computed. In this study, the hypercentral potentia...

Description
Summary:Triply heavy Ω ccc and Ω bbb baryons are studied in the framework of the nonrelativistic quark model based on the ansatz approach in hypercentral constituent quark model. The masses of the ground and excited states of the Ω ccc and Ω bbb baryons are computed. In this study, the hypercentral potential is regarded as a combination of the color Coulomb plus linear confining term and the six-dimensional harmonic oscillator potential. Also, we 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. The Regge trajectories for these baryons are plotted in ( n , M 2 ) and ( J , M 2 ) planes which are helpful to determine the unknown quantum number and J P values. A detailed comparison with previous calculations is given.
