关于γ-γ-> γ '-π^+-π^-的Belle数据的另一种解释
An alternative interpretation of Belle data on γ-γ-> η'-π^+-π^-
摘要:
Belle对γ-γ-> η '-π-π的数据是用一个宽的J^{PC}=0^(-+)信号重新拟合的,该信号峰值在2250-2300 MeV的质量范围内,但没有η(1760)。这个宽的0^(-+)信号有可能与晨星和皮尔登最初预测的0^(-+)胶球相一致。X(1835)被证实具有谐振相位变化。
英文摘要:
Belle data on gamma-gamma -> eta'-pi-pi are refitted using a broad J^{PC}=0^(-+) signal peaking in the mass range 2250-2300 MeV, but without η(1760). There is the possibility that this broad 0^(-+) signal may be identified with the 0^(-+) glueball predicted originally by Morningstar and Peardon. The X(1835) is confirmed to have a resonant phase variation.
