Heavy mesons in the Nambu-Jona-Lasinio model

  • We propose an extended Nambu-Jona-Lasinio model to include heavy mesons with heavy quark symmetry. The quark current-current interaction is generalized to include the heavy quark currents. In order to comply with the heavy quark spin symmetry at the heavy quark limit, the dependence of the quark mass on the interaction strength is introduced. The light and heavy pseudo-scalar and vector mesons, their masses and the weak decay constants are calculated in the unified frame.

Heavy mesons in the Nambu-Jona-Lasinio model

    Corresponding author: DENG Wei-Zhen,

Abstract: We propose an extended Nambu-Jona-Lasinio model to include heavy mesons with heavy quark symmetry. The quark current-current interaction is generalized to include the heavy quark currents. In order to comply with the heavy quark spin symmetry at the heavy quark limit, the dependence of the quark mass on the interaction strength is introduced. The light and heavy pseudo-scalar and vector mesons, their masses and the weak decay constants are calculated in the unified frame.
