Evidence for charm-bottom tetraquarks and the mass dependence of heavy-light tetraquark states from lattice QCD
We continue our study of heavy-light four-quark states and find evidence from lattice QCD for the existence of a strong-interaction-stable I(JP)=0(1+) udc¯b¯ tetraquark with mass in the range of 15 to 61 MeV below D¯B* threshold. Since this range includes the electromagnetic D¯Bγ decay threshold, cu...
