Beschreibungen/Notizen

• In this work, we study systematically the mass splittings of the qqQ¯Q¯ (q=u, d, s and Q=c, b) tetraquark states with the color-magnetic interaction by considering color mixing effects and estimate roughly their masses. We find that the color mixing effect is relatively important for the JP=0+ states and possible stable tetraquarks exist in the nnQ¯Q¯ (n=u, d) and nsQ¯Q¯ systems either with J=0 or with J=1. Possible decay patterns of the tetraquarks are briefly discussed.
