Electromagnetic form factors and structure of the $T_{bb}$ tetraquark

Ivan Vujmilovic, Sara Collins, Luka Leskovec +1

We present the first lattice QCD calculation of electromagnetic form factors of a tetraquark, focusing on the $T_{bb}=bb\bar{u}\bar{d}$ with quantum numbers $I(J^P)=0(1^{+})$. The…
