论文摘要
我们计算了分支近似值内的$λ_C\ \λ_c\tomλ_c\至λπ$的分支比率。发现结果遭受了形式因素的不确定性。为了减少这种不确定性，我们检查了两个渠道的比率，这是$ r = 0.0743 \ pm 0.0014 $。发现由形式因素引起的不确定性大大降低。该注释是为BESIII合作准备的。
We calculated the branch ratios of $Λ_C\to ΛK$ and $Λ_C\to Λπ$ within factorization approximation. It is found that the results suffers from the uncertainties of form factors. To reduce such uncertainties, we checked the ratio of the two channels, which is obtained as $R=0.0743\pm 0.0014$. It is found that the uncertainty caused by form factors is significantly reduced. This note is prepared for the BESIII collaboration.
