The LHCb Collaboration announced the observation of doubly charmed baryon through in 2017. Since then, a series of studies of doubly heavy baryons have been presented. was discovered through nonleptonic four-body decay mode, and experimental data have indicated that the decay modes of are not saturated by two- and three-body intermediate states. In this work, we analyze the four-body weak decays of doubly heavy baryons , and . Decay amplitudes for various channels are parameterized in terms of SU(3) irreducible amplitudes. We point out that branching fractions for Cabibbo-allowed processes , would be helpful to search for and in future measurements at experimental facilities like LHC, Belle II, and CEPC.
