| 英文摘要 | The resonance d-sj (2632) observed by selex, has attracted great interests and meanwhile brought up serious dispute. its spin-parity, so far has not finally determined and if it exists, its quark-structure might be exotic. following the previous literature where d-sj(2632) is assumed to be a radial-excited state of 1(-), we consider the possibilities that it might be a q (q) over bar ground state of 2(+) or the first radial-excited state of 0(+) d-sj(2317) and re-calculate its strong decay widths in terms of the bethe-salpeter equation. our results indicate that there still is a sharp discrepancy between the theoretical evaluation and data. |
