Further study on excited ${\Xi }_{Q{Q}^{\prime }}$ via photoproduction at CEPC and FCC-ee

Hong-Hao Ma, Juan-Juan Niu, Lei Guo

Within the framework of NRQCD, the photoproduction of doubly heavy baryons ${\Xi }_{cc}$, ${\Xi }_{bc}$, ${\Xi }_{bb}$ and their $P$-wave excited states has been systematically investigated. The…
