Lambda polarization and single-spin left-right asymmetry in diffractive hadron-hadron collisions
Year: 2000
Type: article
Abstract: We discuss lambda polarization and single-spin left-right asymmetry in diffractive hadron-hadron scattering at high energies. We show that the physical picture proposed in a recent Letter is consistent with the experimental observation that $\ensuremath{\Lambda}$ polarization in the diffractive process $p\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\Lambda}{K}^{+}p$ is much higher than that in the inclusive reaction $p\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\Lambda}X.$ We make predictions for the left-right asymmetry ${A}_{N}$ and for the spin transfer ${D}_{\mathrm{NN}}^{\ensuremath{\Lambda}}$ in the single-spin process $p(\ensuremath{\uparrow})\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\Lambda}{K}^{+}p$ and suggest further experimental tests of the proposed picture.
