Abstract
The newly observed resonance by BELLE is believed to be a tetraquark bound state made up of . We propose the bottomed analog of this bound state, namely, by replacing one of the charm quarks by a bottom quark, thus forming . One of the is doubly charged. The predicted mass of is around 7.6 GeV. This doubly-charged bound state can be detected by its decay into . Similarly, we can also replace both charm quark and antiquark of the by bottom quark and antiquark, respectively, thus forming the bottomonium analog of . The predicted mass of is about 10.7 GeV.
