| 英文摘要 | With a combined analysis of data on gamma(5S) -> h(b)(1P, 2P)pi(+)pi(-) and gamma(5S) -> B-(*())(B) over bar (()*()) pi in an effective field theory approach, we determine resonance parameters of Z(b) states in two scenarios. In one scenario we assume that Z(b) states are pure molecular states, while in the other one we assume that Z(b) states contain compact components. We find that the present data favor that there should be some compact components inside Z(b)((r)) associated with themolecular components. By fitting the invariant mass spectra of gamma(5S) -> h(b)(1P, 2P)pi(+)pi(-) and gamma(5S) -> B-(*())(B) over bar*pi, we determine that the probability of finding the compact components in Z(b) states may be as large as about 40 %. |
