论文摘要
在这项工作中，我们研究了$λ_c\ toπ^0ηp$的过程，考虑到中间标量状态$ a_0（980）$，可以从$ s $ s $ - 波型伪苏斯卡尔级 - 二型型互动中动态生成。我们已经计算了$π^0η$不变的质量分布，发现与$ a_0（980）$相关的重要结构。我们还大致估计了分支分数$ \ MATHCAL {B}（λ_c\toπ^0ηp）\ sim 10^{ - 4} $。我们鼓励我们的实验同事在此反应中测量$λ_c\ toπ^0ηp$以搜索状态$ A_0（980）$。
In this work, we have investigated the Cabibbo-suppressed process $Λ_c \to π^0ηp$, by taking into account the intermediate scalar state $a_0(980)$, which could be dynamically generated from the $S$-wave pseudoscalar-pseudoscalar interaction within the chiral unitary approach. We have calculated the $π^0η$ invariant mass distribution, and found that there is a significant structure associated to the $a_0(980)$. We have also roughly estimated the branching fraction $\mathcal{B}(Λ_c \to π^0ηp) \sim 10^{-4}$. We encourage our experimental colleagues to measure the process $Λ_c \to π^0ηp$ for searching for the state $a_0(980)$ in this reaction.
