Mass spectra and electromagnetic characteristics of the $K^{(\ast )}{\bar{D}}^{(\ast )}$ and $K^{(\ast )}{D}^{(\ast )}$ molecular tetraquarks from the coupled-channel dynamics

Jia-Ning Cui, Fu-Lai Wang

Motivated by the observation of numerous charmed-strange hadrons lying close to the $K^{(\ast )}{\bar{D}}^{(\ast )}$ and $K^{(\ast )}{D}^{(\ast )}$ thresholds, we systematically investigate their mass…
