LHCb discovers 5 new baryons

Excited states of the Omega_c baryon. The ground state and one excited state were known already, now 5 additional were discovered with amazingly clear peaks. The significances are 20 sigma for the first 4 peaks and 10 sigma for the 5th peak. A wide 6th state might hide at 3200 MeV.
