Heavy axial-vector structures bbc‾c‾
The fully heavy axial-vector diquark-antidiquark structures bbc‾c‾ are explored by means of the QCD sum rule method. They are modeled as four-quark mesons T1 and T2 composed of bTCσμνγ5b, c‾γνCc‾T and bTCγμγ5b, c‾Cc‾T diquarks, respectively. The spectroscopic parameters of the tetraquarks T1 and T2...
