Non-leptonic two-body weak decays of ${\Lambda }_c(2286)$

Abstract

We study the non-leptonic two-body weak decays of ${\Lambda }_c^{+}(2286)\to {\mathbf{B}}_{n}M$ with ${\mathbf{B}}_n$ ($M$) representing as the baryon (meson) states. Based on the $SU(3)$ flavor symmetry, we can describe most of the data reexamined by the BESIII Collaboration with higher precisions. However, our result of $\mathcal{B}({\Lambda }_c^{+}\to p{\pi }^0)=(5.6\pm 1.5)\times 10^{-4}$ is larger than the current experimental limit of $3\times 10^{-4}$ (90\% C.L.) by BESIII. In addition, we find that $\mathcal{B}({\Lambda }_c^{+}\to {\Sigma }^{+}{K}^0)=(8.0\pm 1.6)\times 10^{-4}$, $\mathcal{B}({\Lambda }_c^{+}\to {\Sigma }^{+}{\eta }^{\prime })=(1.0_{-0.8}^{+1.6})\times 10^{-2}$, and $\mathcal{B}({\Lambda }_c^{+}\to p{\eta }^{\prime })=(12.2_{-8.7}^{+14.3})\times 10^{-4}$, which are accessible to the BESIII experiments.
