Abstract

We study the three-body baryonic decay Bˉ0Λc+pˉπ0 \bar{B}^{0}\rightarrow\Lambda^+_c \bar{p} \pi^0 based on the factorization approach. The most important Feynman diagrams for this decay mode are factorizable and non-factorizable contributions, so that the former plays the key role in the decay amplitude and the latter affects the amplitude coefficient a2a_2. We calculate the decay branching ratio for some values of a2a_2 in the range of 0.160.400.16-0.40 and we find that the value of a2=0.17a_2=0.17 leads us to the result of (1.50±0.21)×104(1.50\pm0.21)\times10^{-4} which evidently agrees with the experimental result (1.55±0.17±0.08)×104(1.55\pm0.17\pm0.08)\times 10^{-4} reported by BABAR
