In this work, we study systematically the mass splittings of the $$qq\bar{Q}\bar{Q}$$qqQ¯Q¯ ($$q=u$$q=u, d, s and $$Q=c$$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 $$J^P=0^+$$JP=0+ states and possible stable tetraquarks exist in the $$nn\bar{Q}\bar{Q}$$nnQ¯Q¯ ($$n=u$$n=u, d) and $$ns\bar{Q}\bar{Q}$$nsQ¯Q¯ systems either with $$J=0$$J=0 or…
