Weak Decays of Doubly Heavy Baryons: Multi-body Decay Channels

Yu-Ji Shi, Wei Wang, Ye Xing +1

The newly-discovered ${\Xi }_{cc}^{++}$ decays into the ${\Lambda }_c^{+}{K}^{-}{\pi }^{+}{\pi }^{+}$, but the experimental data has indicated that this decay is not saturated by any two-body intermediate state…
