Search for $CP$ violation and measurement of branching fractions and decay asymmetry parameters for ${\Lambda }_c^{+}\to \Lambda h^{+}$ and ${\Lambda }_c^{+}\to {\Sigma }^0{h}^{+}$ ($h=K,\pi$)

Belle Collaboration, L. K. Li, W. Shan +187

We report a study of ${\Lambda }_c^{+}\to \Lambda h^{+}$ and ${\Lambda }_c^{+}\to {\Sigma }^0{h}^{+}$ ($h=K,\pi$) decays based on a data sample of 980~${\mathrm{fb}}^{-1}$ collected with the Belle detector at the KEKB energ…
