Spin correlations in the reaction "pi \vec D --> \vecΣΘ^+" and the parity of Theta^+

Abstract

We analyze two types of spin observables in the reaction $\pi \vec{D}\to \vec{\Sigma }{\Theta }^{+}$ near the threshold. One concerns the spin-transfer coefficients $K_x^x$ and $K_z^z$. The second one 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.
