英文摘要	In the present work, we investigate the production mechanism of the Z(b)(10610) and Z(b)(10650) states from the Upsilon(5S,6S) decays. Two types of bottom-meson loops are discussed. We show that the loop contributions with all intermediate states being the S-wave ground state bottom mesons are negligible, while the loops with one bottom meson being the broad B-0(*) or B-1(') resonance could provide the dominant contributions to the Upsilon(5S) -> Z(b)(('))pi. It is found that such a mechanism is not suppressed by the large width of the B-0 / B-1(') resonance. In addition, we also estimate the branching ratios for the Upsilon(6S) -> Z(b)(('))pi which could be tested by future precise measurements at Belle-II.
