NLO results with operator mixing for fully heavy tetraquarks in QCD sum rules

Abstract We study the mass spectra of Q ¯ Q Q ¯ Q $$ \overline{Q}Q\overline{Q}Q $$ (Q = c, b) systems in QCD sum rules with the complete next-to-leading order (NLO) contribution to the perturbative QCD part of the correlation functions. Instead of meson-meson or diquark-antidiquark currents, we use...
