Spin analysis of the chisub(d) states

Creators

  • 1. Institute of Nuclear Physics, Krakow (Poland)

Description

Angular correlations in the cascade reaction e+e- -> Y' -> γchisub(b) -> γγY -> γγ(μ+μ- or e+e-) have been used to investigate the spins of two of the chisub(b) states. A dependence of the radiative transition rates on the chisub(b) spins has been examined. The results support the chisub(b) spins predicted by the potential models of heavy quarkonia. (orig.)
