Description

The results of a study of the spin density matrix of the rho0 meson in a quark jet produced in deep inelastic ν(nu-bar)N scattering, obtained by means of the Fermilab 15-ft bubble chamber, are presented. As a result of analysis of the rho0-meson spin alignment in the helicity coordinate system it was found that rho0 mesons in a quark jet are produced predominantly longitudinally polarized (with zero helicity). The rho0-meson spin density matrix element rho00 in this coordinate system was found to be 0.63 +- 0.15. From study of the P-odd rho0-meson spin density matrix elements Im (rho10+rho/sub -/10) and Im rho1/sub -/1 indications of the polarization of the fragmented quark have been obtained for the first time
