Observation of Cabibbo-Suppressed Two-Body Hadronic Decays and Precision Mass Measurement of the ${\Omega }_c^0$ Baryon

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1082

The first observation of the singly Cabibbo-suppressed ${\Omega }_c^0\to {\Omega }^{-}{K}^{+}$ and ${\Omega }_c^0\to {\Xi }^{-}{\pi }^{+}$ decays is reported, using proton-proton collision data at a center-of-m…
