$T_{cc}$ and Hidden Charm Tetraquarks $1^{+}$ and $0^{+}$in QCD sum rules and Heavy-Quark Spin Symmetry

Semra Sari Ferah, Altug Ozpineci

In this work, $T_{cc}$ double charm tetraquark and $1^{+}$ and $0^{+}$ hidden charm tetraquarks are studied within the QCD sum rules framework. In the heavy-quark limit, the $1^{+}$…
