| Abstract: | The newly observed Z(+)(4433) resonance by BELLE is believed to be a tetraquark bound state made up of (cu)((c) over bar(d) over bar). We propose the bottomed analog of this bound state, namely, by replacing one of the charm quarks by a bottom quark, thus forming Z(bc)(0,+/-,+/-+/-). One of the Z(bc) is doubly charged. The predicted mass of Z(bc) is around 7.6 GeV. This doubly charged bound state can be detected by its decay into B-c(+/-)pi(+/-). Similarly, we can also replace both charm quark and antiquark of the Z(+)(4433) by bottom quark and antiquark, respectively, thus forming Z(bb) the bottomonium analog of Z(+)(4433). The predicted mass of Z(bb) is about 10.7 GeV. |
