Investigating tetraquarks composed of $$us\bar{d}\bar{b}$$ usd¯b¯ and $$ud\bar{s}\bar{b}$$ uds¯b¯
Abstract In the framework of the quark delocalization color screening model, we investigate tetraquarks composed of $$us\bar{d}\bar{b}$$ usd¯b¯ and $$ud\bar{s}\bar{b}$$ uds¯b¯ in two structures: meson-meson structure and diquark–antidiquark structure. Neither bound state nor resonance state is found...
