Polarization states of K*-meson in the D→ eνK*decay

In terms of weak hadron form factors the elements of K-meson density matrix in the D→eνksup(*) process are calculated. Structural functions determining the Ksup(*) meson production with vector and tensor polarizations have been found. Elements of density matrix have been found for two cases: 1) in finite state only K-meson is registered; 2) in finite state electron and K-meson energy is registered. The numerical estimates of density matrix elements performed for the first case demonstrate sensitivity of these polarization characteristics for details used in form factors calculations of the D→Ksup(*) transition
