Abstract
The B0→ηcK+π− decay rate is calculated using the factorization approach, the Dalitz plot analysis technique is used to describe this process. One of the decay mechanisms involves an interesting exotic Zc(4100)− meson, besides, the non-resonant contribution and the contribution from neutral excited kaons K⁎0(892), K⁎0(1410), and K⁎0(1680) are taken into account. The overall branching fraction is obtained to be B(B0→ηcK+π−)=(5.58±1.19)×10−4. The dominant contribution to this result is the non-resonant one.
