Observation of New States Decaying into ${\Lambda }_c^{+}{K}^{-}{\pi }^{+}$ and ${\Lambda }_c^{+}{K}_S^0{\pi }^{-}$

R. Chistov

We report the first observation of two charmed strange baryons that decay into ${\Lambda }_c^{+}{K}^{-}{\pi }^{+}$. The broader of the two states is measured to have a mass of $2978.5\pm 2.1\pm 2.0$ Me…
