The combined results suggest that the color-triplet configuration becomes more important when the mass difference between the quarks and antiquarks increases. We find three stable states that lie below the thresholds of two pseudoscalar mesons. They are the \begin{document}$IJ^{P}=01^{+}$\end{document} \begin{document}$nn\bar{b}\bar{b}$\end{document} tetraquark, \begin{document}$IJ^{P}=00^{+}$\end{document} \begin{document}$nn\bar{c}\bar{b}$\end{document} tetraquark, and \begin{document}$J^{P}=1^{+}$\end{document} \begin{document}$ns\bar{b}\bar{b}$\end{document} tetraquark."> Doubly heavy tetraquarks in an extended chromomagnetic model -
