摘　　要：Here,we study the production of charmonium pentaquarks cc¯qqq from bottom baryon and B-meson decays under the flavor SU(3)symmetry.Decay amplitudes for various processes are parameterized in terms of SU(3)irreducible nonperturbative amplitudes.Numerous relations between decay widths are deduced.Moreover,the strong decays of pentaquarks are considered.Our results can be tested in future measurements at LHCb,Belle II,and CEPC.Once decay branching fractions are measured,this study will be useful for the exploration of new decay channels and pentaquark states.
