Decay width of the Θ+(1540) in 5-quark dynamical calculation Original Research Article

The mass and decay width of the Θ+ are calculated in a constituent quark model comprising View the MathML source quarks. With the use of a one-gluon exchange quark-quark interaction, the absolute mass is calculated to be larger than 2 GeV, increasing in order of the spin-parity, View the MathML source, View the MathML source and View the MathML source. The characteristic feature of the wave function is also discussed.
