Determining pentaquark quantum numbers from strong decays

Journal Article (Journal Article)

Assuming that the recently observed Θ+ and Ξ- are members of an anti-decuplet of SU(3), decays to ground state baryons and mesons are calculated using an effective Lagrangian which incorporates chiral and SU(3) symmetry. We consider the possible quantum number assignments JΠ=12±,32± and calculate ratios of partial widths. The branching ratios of exotic cascades can be used to discriminate between even and odd parity pentaquarks. © 2004 Published by Elsevier B.V.
