Description
Rich spectrum is expected for charmed baryons in the quark model, yet many states especially those containing strange quarks has not been experimentally established. The mass of B meson is sufficient to decay to two charm bayrons, especially $\Xi_c$ and $\Lambda_c$. B-factories have observed a serious of decays from a B meson to two charmed baryons. In recent years, LHCb implements several studies of B decays with two charmed baryon daughters, such as $B^{0/+} \to \Lambda_c \Lambda_c K^{0/+}_{(S)}$. Intermadiate states including excited $\Xi_c$ are also observed or show evidence. For such decays above, the branching fractions are measured via a relative branching fraction method. For future, more double charmed baryons decays are expected to be studied in LHCb.
