Searching for doubly charmed baryons from meson decays*

Abstract In this study, we investigate the production of doubly charmed baryons from anti-bottom charmed mesons. Using the effective Lagrangian approach, we discuss triangle diagrams at the hadronic level to access the branching ratios of . Apparently, the specific process occupies the largest possibility on the order of . In addition, although the production of undiscovered is Cabibbo suppressed in , its branching ratio can still reach a level of . These results are expected to provide valuable support for future experiments.
