Measurements of ${\Lambda }_c^{+}$ Branching Fractions of Cabibbo-Suppressed Decay Modes involving $\Lambda$ and ${\Sigma }^0$

The BABAR Collaboration, B. Aubert

We measure the branching ratios of the Cabibbo-suppressed decays ${\Lambda }_c^{+}$ $\to$ $\Lambda$ $K^{+}$ and ${\Lambda }_c^{+}$ $\to$ ${\Sigma }^0$ $K^{+}$ %(measured with improved accuracy). relative to the Cabibbo…
