摘要:

考虑到涵盖$Ss, Sp$和$Ps$通道的全部六个阈分波振幅$f_1, ..., f_6$,导出了$pp \to ppω$末态质子的极化和自旋关联的模型无关公式.结果表明,这些测量的最终状态自旋可观的,只采用非偏振光束和非偏振的目标,可以用来补充测量,在双微分水平,建议较早[物理评论\textbf{C78},01210(R)(2009)],使所有六个分波振幅可以确定经验。

英文摘要:

Model independent formulae are derived for the polarizations and spin correlations of protons in the final state of $pp \to ppω$, taking into consideration all the six threshold partial wave amplitudes $f_1, ..., f_6$ covering $Ss, Sp$ and $Ps$ channels. It is shown that these measurements of the final state spin observables, employing only an unpolarized beam and an unpolarized target, may be utilized to complement measurements, at the double differential level, suggested earlier [Phys. Rev. \textbf{C78}, 01210(R)(2009)] so that all the six partial wave amplitudes may be determined empirically.
