The J=3/2 Θ* partner to the Θ(1540) baryon

Dudek, J. J. · Close, F. E.

Original · EN

If the exotic baryon Θ(1540) is ududs with Jᵖ = 1/2+, we predict that there is a 0bar with Jᵖ = 3/2+ containing a Θ*(1540-1680). The width Γ(Θ* → KN) is at least a factor of three larger than Γ(Θ). The possibilities of Θ* → KNπ or Θγ via M1 and E2 multipoles are discussed.
