Masses of doubly heavy-quark baryons in an extended chromomagnetic model

Understand

We extend the chromomagnetic model by further considering the effect of color interaction.

• The effective mass parameters between quark pairs ($m_{qq}$ or $m_{q\bar{q}}$) are introduced to account both the effective quark masses and the color interaction between the two quarks.
• Using the experimental masses of hadrons, the quark pair parameters are determined between the light quark pairs and the light-heavy quark pairs.
• Then the parameters of heavy quark pairs ($cc$, $cb$, $bb$) are estimated based on simple quark model assumption.
