论文摘要
衰减中最终粒子的角分布$λ_c^+\ to k^ - \,δ(1232)^{++} \ to k^ - \,p \,p \,π^+$,讨论了偏光charmed baryon的π^+$。提出了不对称的,以确定$λ_C^+$偏振矢量的组件。在弯曲晶体中重子通道过程中极化的进动角与这些不对称性直接相关。 $λ_c^+\ to K^ - \,δ(1232)^{++} $衰减的衰减速率和不对称参数是在POL模型中计算的,并与实验进行了比较。
Angular distribution of the final particles in the decay $Λ_c^+\to K^- \, Δ(1232)^{++} \to K^- \, p \, π^+$ of the polarized charmed baryon is discussed. Asymmetries are proposed which allow for determination of the components of the $Λ_c^+$ polarization vector. The precession angle of the polarization in the process of baryon channeling in a bent crystal is directly related to these asymmetries. The decay rate and asymmetry parameter for the $Λ_c^+\to K^- \, Δ(1232)^{++}$ decay are calculated in the pole model and compared with experiment.
