基态粲重子$\Lambda_c$的衰变现在接近完全绘制出来。在本文中，我们讨论了一些悬而未决的问题，其答案可以帮助阐明弱过程对这些衰变的贡献，在晶格QCD中的跃迁形状因子等量的计算，以及在丢失的衰变模式，如$\Lambda^* \ell^+ \nu_\ell$，其中$\Lambda^*$是一个激发共振。本文的讨论部分地对应于以前对包含$D_s$衰变的分析。
The decays of the ground-state charmed baryon $\Lambda_c$ are now close to being completely mapped out. In this paper we discuss some remaining open questions, whose answers can help shed light on weak processes contributing to those decays, on calculations of such quantities as transition form factors in lattice QCD, and on missing decay modes such as $\Lambda_c \to \Lambda^* \ell^+ \nu_\ell$, where $\Lambda^*$ is an excited resonance. The discussion is in part a counterpart to a previous analysis of inclusive $D_s$ decays.
