Observation of excited ${\Omega }_c^0$ baryons in ${\Omega }_b^{-}\to {\Xi }_c^{+}{K}^{-}{\pi }^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +959

The first observation of the ${\Omega }_b^{-}\to {\Xi }_c^{+}{K}^{-}{\pi }^{-}$ decay is reported using $pp$ collision data at centre-of-mass energies of 7, 8 and 13\,$\mathrm{TeV}$ collected by the LHCb e…
