Analytical Determination of Mass and Magnetic Moment of Baryons in Diquark Model

Abstract

So far, many constituent quark models have been applied to describe the internal configuration of light and heavy baryons and also for determining their static properties Among all static quantities, the mass and the magnetic moment of baryons are the most interesting observables which provide direct information on the dynamics of strong interaction and color confinement phenomenon. In this work, through the quark–diquark model we analytically compute the mass and the magnetic moment of light and heavy baryons in their ground state. To this aim, we use the Bethe–Salpeter equation in the presence of Hellmann potential with the onepionexchange contribution to determine the mass and the wave function of baryons. Using the spin-flavor structure of constituent quarks we calculate the magnetic moment of light, single and double heavy baryons and compare them with existing data and other modeldependent predictions. We will also predict the mass and the magnetic moment of unobserved triply heavy baryons relevant for the present and future high energy colliders.
