Spin correlations in the reaction pi(+/-)(D)over-right-arrow ->(Sigma)over-right-arrow(+/-)Theta(+) and the parity of Theta(+)

Kampfer, B.; Titov, A. I.

We analyze two types of spin observables in the reaction pi D->->Sigma(->)Theta(+) near the threshold. One concerns the spin-transfer coefficients K-x(x) and K-z(z). The second is the deuteron spin anisotropy. These observables are sensitive to the Theta(+) parity and can be used as a tool for the Theta(+) parity determination.
