$\bar{b}\bar{b}ud$ and $\bar{b}\bar{b}us$ tetraquarks from lattice QCD using symmetric correlation matrices with both local and scattering interpolating operators

Constantia Alexandrou, Jacob Finkenrath, Theodoros Leontiou +3

We study the $\bar{b}\bar{b}ud$ tetraquark with quantum numbers $I(J^P)=0(1^{+})$ as well as the $\bar{b}\bar{b}us$ tetraquark with quantum numbers $J^P=1^{+}$ using lattice QCD.…
