Representation mixing of exotic baryons in {10￣} and {27}

Abstract

We estimate the masses and the widths of the exotic baryons in {10bar} and {27} multiplets mixed with {8} and/or {35} multiplets. Using this representation mixing method, we calculate the mass of (Theta^+), 1539 MeV and the decay width of (Theta^+), 4MeV. In the experiments, mass of (Theta^+)is near by 1540MeV and the decay width is 0.36 ~ 26M eV . For the mass, our result is in good agree- ment with the experiments. For the decay width, we calculate the narrow results.
