Spectra and strong decays of open charm-bottom $c\bar{b}q\bar{q}$ tetraquarks in an unequal-mass Born-Oppenheimer framework

Bowen Kang, Xi Xia, Tao Guo

We investigate the mass spectra and strong decay channels of $S$-wave open charm-bottom $c\bar{b}q\bar{q}$ ($q=u,d,s$) tetraquarks within the Born-Oppenheimer approximation. Exte…
