Study of Baryon Spectroscopy Using a New Potential Form

Abstract

In the present work, the nonrelativistic quark model is applied to study baryon systems, where the constituent quarks are bound by a suitable hyper central potential. We proposed a new phenomenological form of the interaction potential, digamma-type potential. Using the Jacobi coordinates, the three-body wave equation is solved numerically to calculate the resonance states of theN, Δ, Λ, andΣbaryon systems. The present model contains only two adjustable parameters in addition to the quark masses. Our theoretical calculations are compared to the available experimental data and Cornell potential results. The description of the spectrum shows that the ground states of the considered light and strange baryon spectra are in general well reproduced.

Spectroscopy of ${\mit \Omega }_{cc}$, ${\mit \Omega }_{bb}$ and ${\mit \Omega }_{bc}$ Baryons in Hypercentral Constituent Quark Model via Ansatz Method

“…By considering baryon as a three-body system, in the center-of-mass frame (R cm = 0), the internal quark motion is described by the Jacobi coordinates, ρ and λ [28], defined as:…”

Study of Electromagnetic Properties of Light Baryons in the Hypercentral Approach

“…The baryon structures are recently studied by various constituent quark models [1,2,3,4,5,6,7,8,9,10]. Theoretically, there exist serious discrepancies between the quark model and experimental data particularly in the predictions of baryon magnetic moments.…”
