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

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. Extending our previous study of hidden heavy flavor tetraquarks, we account for the unequal-mass heavy quark sources and construct the effective...
