关于π_c(3055)^+和π_c(3123)^+的一个注记
A note on Ξ_c(3055)^+ and Ξ_c(3123)^+
摘要:
巴巴尔合作公司宣布了两个新的兴奋的魅力重子$Ξ_c(3055)^+$和$Ξ_c(3123)^+$。我们研究了它们的强衰变,假设它们是D波态。通过将计算结果与实验值进行比较,排除了某些赋值,得到了$Ξ_c(3055)^+$和$Ξ_c(3123)^+$的总宽度.我们还提出了一些可能的衰变模式,这将有助于确定$Ξ_c(3055)^+$和$Ξ_c(3123)^+$的性质。
英文摘要:
Babar Collaboration announced two new excited charmed baryons $Ξ_c(3055)^+$ and $Ξ_c(3123)^+$. We study their strong decays assuming they are D-wave states. Some assignments are excluded by comparing our numerical results with the experimental values of the total widths of $Ξ_c(3055)^+$ and $Ξ_c(3123)^+$. We also suggest some possible decay modes, which will be helpful to determine the properties of $Ξ_c(3055)^+$ and $Ξ_c(3123)^+$.
