Since this paper was written two new discoveries were made at CERN. In the first,
Ds3*(2860)ˉ, a meson that contains a charm anti-quark and a strange quark, was found. .
The number 2860 is the mass of the particle in the units of MeV/c2.
bottom, one strange, and one down quark, in two higher energy states. They observed signatures for two particles at
masses of 5935 and 5955 mega-electron-volts
